Sounds like a bad plugin or theme. Have you tried:
– switching to the default theme to rule out any theme-specific problems.
– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.
– re-uploading all files & folders – except the wp-content folder and wp-config.php & root .htaccess files – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.
Great advice thank you. I’ve done your suggestions for the plugin and theme problems but the error is still there. I’m a bit nervous about your final suggestion re-uploading all files & folders etc – is there a step by step guide that I can follow?
What makes you nervous about it? You are simply uploading a fresh set of WordPress core files. As long you stay away from the wp-content folder and wp-config.php & root .htaccess files, you’ll be fine.
Great – thank you so much for your help.
