Hello,
The error message preg_match_all that you see on the header section of the page is most likely caused by a mismatch in the parentheses of some of your focus keywords.
Sometimes, you might use parentheses to group words together or to indicate a variation – however, if you forget to close a parenthesis, or if you have an extra one, this can cause the error message to appear.
To fix this problem, you need to check the focus keyword of the page and make sure that every parenthesis is matched with a closing one.
Let us know how this goes.
