dvharrison Posted January 16, 2016 Share Posted January 16, 2016 Hi All I have installed SEO header tags on my website operating on Oscommerce 2.3.4. We did have Ultimate SEO 5 installed, but uninstalled it. However after installing and configuring Header Tags, everything works fine, except that on the admin panel under Configuration > Header Tags SEO, I keep getting the following warning appear : Warning: call_user_func() expects parameter 1 to be a valid callback, function 'tep_reset_cache_data_usu5' not found or invalid function name in http://ourwebname\admin\includes\functions\general.php on line 1328 Line 1328 is: return call_user_func($function, $parameter); I have uninstalled, reinstalled, gone through all my changes, run searches on usu5, tep_reset_cache_data and call_user_func and even gone through the database. There is an usu_cache table in our database. I did drop it but its made no difference (I have since imported it again). I would appreciate any help or advice. Thanks in advance :) Quote Debbie Harrison Link to comment Share on other sites More sharing options...
