I disabled the Wordpress SSO and it seems to fix the issue, but I REALLY need that plugin!

Glad to see that the cause of the error has been identified. As mentioned above by @Jim M you will have to contact the author of the aforementioned app for further assistence.

I am reaching out to him. It still puzzles me why this happened just today as I was not working on the site, didn't update anything, didn't install anything, etc.

You'd need to ask them that question

I don't know if it is a solution but here is what has happened.

On Sunday, my site was not loading anymore. I reached out to my host who couldn't find anything. It might have been a glitch or a hiccup but nothing serious. However, while searching, the host pointed that as i am using Cloudflare, I should have the side Proxied, which it wasn't, so I changed it to DNS.

Looking at the timeline, I started having issues (and reports from members) on Monday morning. I never made the connection with the Cloudflare settings.

Even though disabling the Wordpress SSO plugin fixed the issue "temporarily", it would not let the users log in with their WP login, so it was not a solution. Re-enabling it SEEMED to fix the initial issue, but it was short-lived and it was intermittent for some members and not others. While still waiting for Stuart to reply to the help request, I remembered that "Proxied" setting that was changed just before the problems arrived.

So, I went back to Cloudflare, and changed the setting back to "not-proxied" and it looks like everything is back to normal; people can post, respond, react, etc.

So I am sharing this in case it could help others.

Glad to see that the issue has been solved and thank you for the update with the solution.

Hard to say if it is a solution or a coincidence! 🙂

Darn. It was all fixed until now.

I got that whole thread appearing in the box to type my response AND I can’t react.

Based on the “solution” that worked earlier, I checked Cloudflare. The Proxied was not changed. I paused Cloudflare for a minute and reactivated it.

That seems to have solved the “whole thread” appearing in the box when I am posting BUT it won’t post when I click SUBMIT. Also, I still can’t react without getting a popup saying I don’t have permission.

I disabled and re-enabled the SSO plugin (just in case), and now the whole thread is back in all my replies, and I still can’t react.

I tried a different browser and it is the same.

Help!

OK, so I have to remember that it should be kept as DNS-only and NOT Proxied.

It is back to normal.

False alarm!

Just so I can refer to this later (or someone else might benefit from it).

I wanted the Proxied setting to help protect my site, but as it seemed to interfere with the Invision forum, I added a Page Rule on Cloudflare to bypass the caching for the forum only.

So far, so good. So I should be able to get the benefits of caching from Cloudflare for my site but let Invision do its work without interference.

Results are so inconsistent.

It worked a while ago. I was able to post, and react. Now, a couple of hours later, it is back to the same problem.

Any suggestion?

From what you posted, it sounds like you have some kind of caching enabled for logged-in members too, not just guests. Is that correct? 🤔

I have WP Fastest Cache installed on my WP installation and Cloudflare, but that has been the case for years.

Id certainly be disabling those and testing before you do anything else

I am not sure why as everything worked fine until last night. If I keep the Cloudflare as DNS only, everything works. What settings should I use on Cloudflare to make it workable as Proxied? Obviously, adding a page rule didn’t work as expected.

Thats something you would really need to speak to cloudflare about
