Getting this error on every page on live website
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'eshop_orderhandle_process' not found or invalid function name in /home/XXX/public_html/wp-includes/plugin.php on line 487
I went through forum, mentioned 6.3.8 has resolved, I am using the same version but getting this error since a week.
The error wasn't there when I first installed and created cart and everything. Now when I want to make website live getting this error.
Deactivating eshop plugin I don't see the error.
I upgraded from 3.5.0 to 3.5.1 hoping it'll resolve the issue but still i see the error message.
