Ok seeing as you have some protection plugin which re-directs the user from the admin panel if they try and access the page, you won't be able to to either.
And seeing as you can't login to disable it, you will have to do it manually via PhpMyAdmin. Follow these instructions:
- Enter PhpMyAdmin
- Open the table called
jos_extensions
(jos is the prefix which may be different for you)
- Find the protection extension you have installed which is causing the redirect and go to edit it.
- You will find a column called enabled. You need to change the value from 1 to 0
You should then be able to login to the Joomla admin panel
Hope this helps
