error_log after uninstalling

Hi there, I’ve been having some issues with 403 errors on my website for the last few days. They only occur when I attempt to update a page that is already posted – its pretty strange. Anyway, I was attempting to find the source of the issue, and recently I uninstalled your plugin – didn’t think anything of it – but looking in my wp-admin folder I noticed and error_log file containing this info:

“

Looking through my database I can see that wp_po_plugins still has tables despite being uninstalled and no longer having any folder or files in wp-content/plugins.

Any help would be much appreciated.
