Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.
If that does not resolve the issue, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).
I was tried buy but work this
I open ftp and go to /query.php and delete 45.line. After another error. I go to 3000.line and delete and 57. line … and problem fix but admin panel not work true .
Im wait but there is no reply and backup posts and delete alll host =(
Well, of course you got another error, you deleted an entire line of code.
Is there any reason why you edited a file rather than doing anything that was posted above?
I cant enter admin panel before but when delete line i can enter admin panel but some plugin not working true for example backup.
Please follow the links in the reply above, none of it requires access to the Dashboard.
