HI esmi,
thank you I have tried most of these.
Changed password in my SQL
took off firewall
Deleted all my plugins except for mailchimp
cleared cache and cookies
checked url

I am sorry I can’t seem to fix my access problem. When I ask for a new password it will not take me to the internet explorer page?
Please could you fix for me?
I downloaded wordpress to my host gator.
Cheers
Elise

And double check your wp-config.php file for white spaces.

Hi I did follow your instructions and actioned it through filezilla and it came up with critical code error. I am starting to wonder if i should just start my blog from scratch again I have wasted so much time trying to gain access to it I could have started again by now.I am at a loss on what to do now?

… and it came up with critical code error.

What was the error message?

… but when I changed that it came up site not available 404 error so I changed the blog url back to what it was …

How did you change your blog url back?

Have you tried:

– resetting the plugins folder by using FTP or whatever file management application your host provides. Sometimes, an apparently inactive plugin can still cause problems.

– switching to the default theme by renaming your current theme’s folder in wp-content/themes using FTP or whatever file management application your host provides.

– re-uploading all files & folders – except the wp-content folder from a fresh download of WordPress. by using FTP or whatever file management application your host provides. (manual upgrade)

I am thinking that you should put the <?php ob_start(); at the starting of the wp-login.php It’s really helps

Don’t do that. No, really, do not modify wp-login.php. Modifying any core file that ships with WordPress is always a really, really, REALLY bad idea.

Walk through what keesiemeijer explained instead. That’s a much better method for solving the OP’s problem of being unable to access the WordPress dashboard.
