If you use Bluehost and tried updating PHP to counter the error messages WordPress generates indicating the version of PHP your running is out of date, you may have subsequently came across the following error message after updating PHP from V5 to 7:
“Your PHP installation appears to be missing the MySQL extension which is required by WordPress”
There’s a simple fix for this issue but its not documented anywhere on Bluehosts Support pages
Just login to the CPanel access the File Manager and rename your PHP.ini file to PHP.ini.bak
