I've searched the forums for a similar situation, but as far as I can tell I've found a unique way to break AMember/WordPress integration. Which is a shame, since I had high hopes for this to be an eventual replacement for my other two sites that use MagicMembers (ptui!). AMember support hasn't responded to my request for help either, which is surprising to me; I'd heard such good things about them. Anyway, here's what happened: AMember was installed after we'd had a custom theme built for our site. Supposedly we were supposed to take the AMember plugin (amember4) and put it in the plugins directory in wp-content, but once we did that, two things happened: one, the front page of the site now has this code appearing at the top: Warning: call_user_func_array() function.call-user-func-array: First argument is expected to be a valid callback, 'widget_wpAmember_init' was given in/home/fiftysha/public_html/wp-includes/plugin.phpon line 403Worse, when I try to access my WordPress Dashboard to, say, configure the plugin or deactivate it or something, I just get this: Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'widget_wpAmember_init' was given in/home/fiftysha/public_html/wp-includes/plugin.php on line 403 Warning: Cannot modify header information - headers already sent by (output started at /home/fiftysha/public_html/wp-includes/plugin.php:403) in/home/fiftysha/public_html/wp-includes/pluggable.php on line 881Not terribly useful. I've tried using FTP to remove the plugin, no change. I've tried reinstalling the plugin - no change. As I said, I've emailed support, but no answer. Anyone familiar with this, or what might be done short of reinstalling everything?
