Problem with saving changes

Hello everybody,

since uploading the project on a online server (till now the project was runing on a local xampp installation) it is not possible to make changes in the template background an save the changes. So maybe if i set the site to "unter construction" in the tp_perfect template an save the change, leaf the template and reload it, the changes are set back to the settings before saving. Can be there e problem with the permissions to a specific folder to make it work?
Thank you to all for any help!
Noce greetings Sylvia

Sorry, but there is no answer in general, it could be everything.
..
1.) Check the configuartion.php file of Joomla ( must have at least 100 lines)
2.) How you transfer the site? Akeeba oder with sql dump
3.) Is your server run the min requirements

Hello,
i used everytime for a lot of times the same method of installation. I finished the project local and made the upload via Fillezilla to the server, saved the database and imported this to the new server via phpmyadmin, adopted the configuration.php file to the server conditions. Joomla on its one function very well, i didn´t find an error, login in backend works, also the frontend works. It´s no problem to make changes for example in an article an safe it, this works. Only if i chance a setting in the jp_perfect template options and safe it the setting will be safed for only one time. If enter the template again and load it the settings are set back. For example: Actually the settings "minify css" are set to no. If ich change it to yes, safe the settings, the setting is safed. If i leave the template options, open it again und reload it the "minify css" is not more set to yes, how it should, it set back to no.

To your answers:
1) configuration.php has 106 lines
2) I transfered the site via filezilla (ftp-upload). I got no error ...
3) In the joomla configuration i found the following entries:

Upload Max Filesize 96M
Post Max Size 96M
Speicherlimit 256M

The server provides PHP version 8.2.3, set as FastCGI (Appache).

Thanks for more help!

Look in the configuration-php to see if there is an entry for a website behind live-site.
If so, remove it: public $live_site = '';
Not all plugins and extensions work with php8.2. Try switching to php8.1.

The entry in the configuration.php is: public $live_site = '';
The PHP Version is now set to 8.1.16.

No effect. Can be there a problem with the server security? I mean the right to make the change in the database? All other changes (menu, articles, modules, ...) in joomla work fine.

With the database I don't think so. If you have activated directory protection at the hoster (safe-guard), you should deactivate this for the Joomla directory. Otherwise problems like this can occur.
