Whenever I try to install or update a wordpress plugin, I get this error:

PCLZIP_ERR_MISSING_FILE (-4)

This is also happening if I edit a template from a layout manager or if I do anything that depends on the /tmp folder.

If I restart Apache, the problem is solved, but only temporarily. After a few minutes to one hour it looks like the access to the /tmp folder is restricted by Apache again.

I also created a custom /tmp folder inside Wordpress content folder, with 755 permission, and settled it in the configuration file, even so I still get the same problem.

Running Apache on CentOS8, using Direct Admin control panel.

Apache does not start changing access to folders after a few minutes or hours. My guess is you are running low on disk space. – John Hanley Apr 19 '22 at 06:11
Disk used is 6Gb out of 34Gb. – user832 Apr 19 '22 at 07:36
