My VPS running on CWPpro version: 0.9.8.1187
I want to upgrade the plugin for WordPress, but after clicking upgrade I get the following error
Update failed: Could not create directory. /home/*/public_html/wp-content/upgrade/classic-editor.1.6.5
I checked the permissions on the /upgrade/ directory and it is 755, which should be fine!
In addition, before, I could upgrade the plugin normally, but recently I suddenly got such an error.
I checked the site's error logs again and found a number of error records as follows
AH01071: Got error 'PHP message: PHP Warning: file_put_contents(): only -1 of 78424 bytes written, possibly out of free disk space in /home/*/public_ html/wp-content/plugins/wp-cache/inc/cache.php on line 1226'
This seems to be running out of space, but my VPS has 160G and I'm only using 41G so far, what's wrong with this and how should I fix it?
