How to Disable a WordPress Plugin via FTP
Open your favourite FTP Program, I recommend using Filezilla if you don’t have one installed already.
FTP into your websites file system, browse the following path:
Yours may be httpdocs, or www instead of public_html.
If you don’t instend on fixing the issue with the plugin, then you can permanently delete the folder, however if you’ve installed a few plugins and not sure whch one is the culprit, then disabling them one by one will help you find the plugin with the issue.
I hope this tutorial has helped you resolve the issue, if you’re still experiencing the same issue, it may a different prolem altogether and we may be able to help you via TeamViewer Remote Support.
