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-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 your current version of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.
I did all steps. The only thing that helped was switching to the default theme. But I cannot use the default theme so have you got any idea what file can be wrong in the current theme?
What theme are you using? Where did you download it from?
I am using Pricerr theme developed by sitemile.com. There can be some conflict between plugin and theme but i do not know what to check
I’m sorry but as you appear to be using a commercial theme, you need to seek support from the theme’s developer/vendor. We do not have access to, nor do we support, commercial products here.
