Error with latest update

HI, I get this warning and cannot enter my website. I have deactivated all the plugins except beaver builder and still have the problem.

Warning: require_once(classes/class-fl-builder.php): failed to open stream: No such file or directory in /hermes/bosnaweb16a/b1107/ipg.wiredleaderscom/wp-content/plugins/bb-plugin_old/fl-builder.php on line 26 Fatal error: require_once(): Failed opening required ‘classes/class-fl-builder.php’ (include_path=’.:/usr/local/lib/php-5.3.29-amd64/lib/php’) in /hermes/bosnaweb16a/b1107/ipg.wiredleaderscom/wp-content/plugins/bb-plugin_old/fl-builder.php on line 26

Hi Jane,

According to your error message, you have renamed the bb-plugin directory to bb-plugin_old. Is there a reason for this?

Can you also provide both temp admin access and FTP access, please?
