1) you set 777 permissions on files and (or) directory. Bring back the rights to the normal state, php runs on the user, so normal human enough to write to the directory user.
2) In the .htaccess file you have variables to change the php setting, for example: php_value or php_flag. If you do not use these variables, then comment out them in .htaccess file, if using, then correctly transferred it to the php.ini file in your root site folder.
What to check after following this guide
After changing settings, make sure the result works not only in the control panel but also for real website visitors or mailbox users. Test without browser cache and avoid changing many settings at once unless you know exactly what each change does.
For hosting, check the domain, website directory, PHP version, database and email. If the website shows an error, review the error logs in the hosting panel.
- make sure files are uploaded to the correct directory;
- check free space and hosting limits;
- test the website after changing settings.
