Have you tried:
– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-related problems?
Thanks for quick reply.
Yes, I have done both (deactivate all plugins, switch to default theme). The problem remains in both cases.
Try re-uploading the wp-admin and wp-includes folders from a fresh download of your current version of WordPress.
Thanks again!
OK, I just downloaded the current version of WordPress, unzipped the file, uploaded the wp-admin and wp-includes folders to my site via ftp.
Exited WordPress, re-entered WordPress.
No change. I get the same error message when I search for any plugin from the dashboard.
Could be a server configuration issue – something you’d need to talk to your hosts about.
No way this is a server config issue. I have 3 different installs (one fresh) on 3 different servers and after the latest WP upgrade I also started getting this error
