Error Message: “Warning: preg_match()”!
-
I’ve been playing around with plugins for event calendar and registration. I was using Events Manager with WP FullCalendar. Then I switched to WP Eventin and Woocommerce.
I realized the first combo was more suitable and decided to deactivate and uninstall Eventin and Woocommerce. But then I started getting this error on the backend and frontend pages:
“Warning: preg_match(): Compilation failed: quantifier does not follow a repeatable item at offset 1 in /home3/techvwat/public_html/newsite2022/wp-includes/class-wp.php on line 231”
When I install WP Eventin and Woocommerce again and even keep them deactivated, the error goes away.
Can someone explain what the error message means and what I can do perhaps in the File Manager to get rid of it so I can hopefully delete those plugins for good?
