Every time you come out with a new version, I've had troubles getting my blog to work again after upgrading!
Now I've given up and tried to uninstall you plugin.
No matter how hard I try to make my blog work after uninstalling it, I keep get the following warning above my comment box:
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'tl_spam_free_wordpress_comments_form' was given in /home/xxxxx/public_html/wp-includes/plugin.php on line 403 - See more at: http://www.buildinganonline.com/blog-engage-review-consider-join-2769/
As soon as your plugin is reactivated, the above disappears.
I've used your plugin's possibility to create the comment form once, but since it looked awful (at my theme), I disabled it immediately again.
I've tried to run the SQL query mentioned above - No luck!
I've tried to re-install it, and deselect all options - No luck!
I've deactivated all other plugin's - No luck!
My support question is: What do I do to end this error?
