Ask Apache Safe Removal

I posted the following a few days ago here on this forum:

“I currently have the Ask Apache Password Protect plugin installed on one of my wordpress blogs.

I am pretty certain it is because this plugin is installed that I am unable to update to the most recent version of WordPress. I am also unable to update any of the other existing installed plugins within this blog.

I have read in many places on the internet including here in this forum of many problems any attempts at removing this plugin can cause. Including no longer being able to access the admin panel and also removing the whole site with a fatal error message.

Please can anyone help me and advise how to remove this plugin safely? I have managed to backup my site using backupbuddy, however this backup obviously includes the AskApache plugin.

Any help would be appreciated – although I have to be certain this will not lock me out of my site.

Many thanks.”

I was sent to this page in response:

http://wordpress.org/extend/plugins/askapache-password-protect/

But I couldn’t find the answer there because I want to remove the plugin totally!

So, I find that this is the most relevant:

http://wordpress.org/support/topic/plugin-askapache-password-protect-uninstall-and-removal?replies=4

However, I can find nothing in my .htaccess file re Askapache.

Is it safe to remove the Askapache plugin via FileZilla – or will I totally mess up my entire site? Please
