• Try disabling and enabling plugins one by one. Does this error disappear after disabling a certain plugin? – kero Commented Dec 4, 2018 at 15:26
• Did you try this solution wordpress/support/topic/…? – Gufran Hasan Commented Dec 4, 2018 at 15:36
• Try this if ( preg_match("#^".preg_quote($match,'#'),"#", $request_match, $matches) || Note also remove the extra ) before || – vikrant zilpe Commented Dec 4, 2018 at 15:37

Sorted by: Reset to default 1

It seems that the permalinks structure has an issue. Please follow below steps to fix it.

Step 1: if possible, back up your WP installation folder. Step 2: Temporary disable all the plugins (important step)

step 3: in the WordPress admin dashboard, go to Settings -> Permalinks

step 4: remember or note down somewhere what you have in the custom permalinks

step 5: temporarily enable (switch to) the default permalink:

step 6: verify the website is working now (not everything, because the plugins are disabled, but the preg_match error should be gone)

step 7: switch back to the custom permalinks setting you had at step 3

step 8: enable back all the plugins

The error will be gone.
