Comment on WordPress Comment Form Title by SEO Dave.
I didn’t make the comment title plugin (it’s copied verbatim from the original plugin), so not sure if that’s an error that the plugin author is familiar with. Did a quick Google search and didn’t find anything.
I assume you have the problem of getting into your site to disable the plugin.
Easiest way to fix this is edit the functions.php file
Save the functions.php file and upload it using FTP into the folder /wp-content/themes/stallion-seo-themes/
This will turn the plugin off because 9 isn’t an option on the Stallion options page (1 = on, 0 = off).
I’ll make another comment with ideas, getting this up ASAP so you can get the site running again without having to delete the entire theme.
