Yes, that way you will be able to identify the app that is not compatible with php 8.
Running the upgrader did it.

That error that you posted above could be due to the fact that you overwrote your forum files with those from the latest version, but didn't run the upgrade. Hopefully upgrading the forum will fix the issue. 
Let us know how it will go.

My question is "Why did you remove the Marketplace" 😄 (joke)
Sorry if the joke sounded lame, but I couldn't resist it. 
My questions are as follow:
What does a typical work day looks like for Charles and what do you do for fun/relaxation when you are outside the office? What do you find most challenging about your position/role?
I am looking forward to the interview. I am sure it will make for an interesting reading. 
 

Greeting everyone,
I'm thrilled to announce that I have secured an opportunity to interview none other than Charles from Invision Community. This is a rare and exciting occasion, and I believe that involving you as our community members can make this experience even more enriching! In recent happenings, I can imagine some of you might have some questions you'd like to see included in this interview.
As I always say, a community is the backbone of any platform. So, I thought: Why not let YOU have a say in the interview? I'm offering all of you a chance to send in your questions, and I'll do our best to include as many as I can in our conversation with Charles.
 
How to Submit Your Questions:
Reply to this topic with your question for Charles. You may PM me your question if you wish to send it anonymously.  Please keep your questions respectful, relevant, and constructive. If you see a question from another member that resonates with you, give it a "like". This will help us gauge the most popular and sought-after questions. You can submit multiple questions, but please post each question separately to make it easier to tally and sort.
Deadline:
The last date for submitting your questions is September 1st. I'll compile them shortly afterward and then proceed with our interview.
A Few Guidelines:
Avoid asking questions that have been answered multiple times in previous communications or on the official FAQ. While I appreciate all the input, I may not be able to include every question in the interview due to time constraints. This is a golden chance to get insights, clarifications, or just to know more about the visions and aspirations of Invision Community from one of its key figures. So, let your curiosity run wild and be a part of this unique opportunity! Looking forward to seeing what you all come up with. 😄 I'm very grateful for this opportunity and hope to receive many questions and interest for this interview.
Best regards,
Cedric (Admin Junkies)

While I empathise with the situation you are currently in,  having 50 3rd party items is probably what is causing you issues in the first place. Its not really possible for us to debug your system for 3rd party item issues.
The issue with the files showing out of date, is likely just that. The files are out of date. You can upload a fresh set from your client area. If this is the latest release, then you would need to run the upgrade afterwards. I realise that puts you in a bit of a circular situation, however, that would go back to the original point. You need to ensure each of your applications are compatible with PHP 8, or things will indeed fail.
It's worth pointing out here, this is a very good reason why you should really add 3rd party items sparingly, and if you are going to use them, you should ensure they are kept up to date in line with keeping your IPS applications up to date. The issue you have here is its been left so long you have no option but to jump both major versions and a PHP version and update 3rd party items at once. This is always going to leave you in a bit of a precarious position, unfortunately.

If you click the Modified files warning message, what do you get?
A word of advice, if I may, it would be best to upgrade your forum to the latest version. 

UI Extensions part 3 of 3 and AMA (sort of!)
 

Let's do some detective work 😄 
Can you post here a list of all the custom apps/plugins that you have installed and maybe we will find the culprit.
If you are going to remove the apps, don't forget to make a backup of their database tables if you want to keep their data after reinstalling them.

Disabling will not be enough for some if they are incompatible with PHP 8. If they are incompatible entirely, you would need to upgrade those prior, or remove them prior. I would advise on checking this first of all

The issue is that one of your custom apps is not compatible with php 8 and/or the latest version of Ipb. Looking at the error message, it affects the topics.

Please ensure that you're using the latest release of the software on PHP 8.0 or PHP 8.1.
 
Please contact your hosting provider as, @Miss_B mentioned, your database is not able to accept the number of connections you're using. You may need to configure your hosting properly or upgrade your package.

It looks like you are using my app.
 

Glad to see that you got it solved. 

I just changed the primary domain on the server, did not move anything. 
thanks, looking at support page everything was ok... cleared system Cache.. that fixed it.. 

Did you do the domain switch only, or did you have to upload your forum files to another folder as well? Was the move within the same host/server? Can you please post here a step by step what you did?
If you can access your Admin Panel, can you go to the Support tab and see if there are things flagged in there that will need fixing?
 

☀️ Welcome to this week's Invision Community Insight! ☀️
Thank you for checking out this quick, round up post. I hope you have a great weekend.
Our updates will continue to be brief. Version 5 has been a big focus for our team so far this year and we are making great progress! We will begin sharing non-technical updates soon.
 
Current Happenings
For our Cloud customers, I did want to draw your attention to our post: Changes to traffic control. Please ask any questions that you have there. 
 
The August release will be ready late this month and will include our spam improvements. Our August release chat is scheduled as well. Join us live if you can or catch the video and discussion in the converted topic after the event. 
 
Changelog
With that said, changes for version 4 are limited for now but for those that like to see what we are up to line by line, here is the changelog for the week for version 4. 
 

It looks like you are using my app.
 

Thank you for sharing the solution. It will help other members who might also run into this issue. 

Thanks @Jim M and @DawPi.
Yes, changing the value of the members_bitoptions column seems to work.
I changed it from 1342242816 to 268500992 (which is the value almost everyone else had there) and that seems to work.

Thank you!

Our software will work on any servers which meet the minimum requirements. The path provided in this topic is merely an example path because that's what the client provided. You will have your own path which needs to be corrected in your PHP settings.

You could share the host log in details amongst yourselves (admins) to avoid situations like this. Or you could look into hosting your forum with Invision and you will not have to worry about stuff like this anymore.
