Great Plugin! (version 4.9, wp 3.0 AND 2.9.2)
I get 3 errors like this whenever I try to edit a page (ANY page):
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'Array' was given in ...wp-includes/plugin.php on line 395
and one like this:
Warning: Cannot modify header information - headers already sent by (output started at ...wp-includes/plugin.php:395) in .../wp-includes/pluggable.php on line 890
and only when using wp 3.0:
when running wp responder cron to send a newsletter, I get the following MySQL error:
[You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ....
INSERT INTO wp_wpr_queue (
htmlenabled) values (...
any chance to fix it???
by the way, I had to change the long plugin-folder's name to just "wpresponder" to make it work.
apart from these errors this plugin is exactly what I needed!
