Hi there,
Normally log in to my site oxfordseating.com by address bar i.e. oxfordseating.com/index.php/dashboard/ - no problems historically.

Suddenly getting this message - Warning: in_array() expects parameter 2 to be array, null given in /home/sites/oxfordseating.com/public_html/updates/concrete5.6.3.4/concrete/core/libraries/localization.php on line 103 followed by 'Error openig translation file"

Any ideas as I can't now log on to the site

Any help appreciated - many thanks
David
