First error:
"The plugin posts-by-tag/posts-by-tag.php has been deactivated due to an error: The plugin does not have a valid header."
This was for all plugins
I ran a secrui scan and big non-specific errors were found:
"Website Errors Detected Critical Contact your Hosting Provider"
The plugins are of course still on the server, all intact in their plugins folder
So a half hour later, I log back in to Admin, and the site is asking me to re-install required plugins.
This isn't the first time this has happened!
THe site is hosted on Godaddy shared hosting
help! What is going on?
