I have switched away from template caching that you had switched on, as that is what was causing you problems. Your server is actually showing service unavailable frequently, which is likely why template caching is having issues. Unless you have good reason to have that switched on, I would leave that switched off

I would suggest removing or at least checking the formatting code you are using on your user groups. Its very very likely that one of these is causing you issues. Something there is so wide its pushing the sidebar down

Yes, that would be expected, as we dont actually store card details. They are stored on the card processor side, and not on our side. Therefore we dont Actually have the current full details to provide them with in order for you to use an existing one for a different provider

Therw would be no way in which to simply add it there in the default software without theme modification. To be honest, given It's the logo area, you would be best to add it to your logo and have a longer banner.

I will create one on your behalf and get it over to sales for you. Someone will be in contact as soon as possible

Its using HVEC encoding, which is what is causing the problem. It does not show on many browsers, other than video. In fact it wont even show in windows without downloading an extention to do so

There is no way in which to do that, unfortunately. It would show only items within that category, not items within its subcategories

There is no "deactivate" button, but I've done this myself in the past. Just create a new group and remove all permissions from it called deactivated. Then you can move members to that group.

The problem you have there is your server is forcing you to https, but you havent set the software to use it. You need to follow the instructions here to switch to https correctly

This is a moderator function, so would be found in moderator permissions. This can be found on the content tab

Yes, they would be prompted the ones that are present only. So, if you delete one, and they have others, they will be prompted for that.

The first thing I see in your erorr log there is that you have 3rd party items loading up which are known not to work in the latest release of the platform (Rules for example). I would advise on not running any at all while you perform your conversion.

Glad to hear this is now working for you.
For others experiencing the same issue, please ensure you are using an apple browser for apple pay. Unfortunately, while using an apple device, it will still only work using their own browser

A patch has now been released to resolve this issue. Please visit support in your admin CP, and select to apply the optional patches present to resolve this.

It would require customisation to that area in order to change the look. We cannot assist with customisation, and if you are unsure its very likely you will need a theme designer to assist you in this. You can see how to edit themes in our guides here (bottom of the list on the left)
 

You would need to upload a fresh set of files from your client area (or just applications/nexus if you are happy to selectively upload). You will then see it available again to install

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.
With regard  your test install, it will not remove from your license when you remove an install. It has to be reset. We would expect people to be installing a test instance in the same location each time. If you do need it to be reset, please let me know

On reading your ticket there, it appears the issue there is connection between your server and twitter, which is something you would need to resolve with your hosting company. 

A ticket has been created to resolve this for you. Please update all details on file and respond to that, and we can get this looked into for you

Thank you for updating those. I have created a ticket for you on this so one of our developers can assist

There is no way in which to force a response to be in a set format at the present time unfortunately

You need to edit your theme in order to remove that. Its on the logos tab of your theme, rather than in the icons and logos section. 
 
The size of the image doesnt really matter. It will resize as needed on a default unaltered theme

When looking at that table, that means that is where its hooked. You can see there is a plugin ID (21) on that table, meaning it is indeed coming from a plugin. The plugin on your system with that ID is "Subscription Privacy"

It looks like its being caused by the newsletters application you have there. Please disable this and test again

You would simply uninstall the themes, then reinstall them from the custom download
