PROBLEM Suddenly reduced size of pages

[islander]

Hello everybody.

This is my first usage of this forum, so I try to do my very best.
Please keep in mind that I am just a user with no deeper knowledge of programming or web side administration.

The GetSimple version is 3.3.16.
The health check says all green, despite GSLOGINSALT and GSUSECUSTOMSALT which read ‘NO’.
The PHP version of the server seems to be 7.4.33 according to PHPinfo.

Everything worked flawlessly a few weeks /months ago. I could work on the content without any issues.
Now I cannot edit already created content beyond a certain size, which is a fraction of size it could have back then. I can use the editor and it tells that there are unsaved changes but nothing happens when I trigger the save button. It also seems that this limitation is purely to the number of characters used and not of its complexity.

Since I did not do any changes in the settings or so, I assume that something happened on the server side. But I can’t figure out what and need to fix that on my side. Unfortunately I don’t even know where to start.
Again, I am just a user and not coming from IT.

Help is much appreciated.
Please let me know, what you need to know in order to help me.

Regards
Gunnar

Hello Hypertexter,
I do not believe v3.3.16 supports php7.4
I would recommend upgrading to the CE version witch supports up to php8.3
Maybe this will resolve your issue.
