Please help with wordpress fatal error

I installed and activated the backup and move plugin and then got this message

Fatal error: Call to undefined function home_url() in /home/coolintr/public_html/mydomainname.com/wp-content/plugins/backup-and-move/backup_and_move.php on line 148

I cannot login to the wordpress cms anymore because whenever I try to I get the above message.

I have deleted the plugin - that did not work
I upadted wordpress - that did not work
I reinstalled the plugin - that did not work

How can I fix this issue?

 

which version of WordPress are you using?

 

I was on an old version when I installed the plugin but now I am on the current version

 

I've WordPress 3.1 on my localhost. I installed the plugin and it successfully installed. I can logout and login without any problem. Tell me which previous version was you using?

 

I am not entirely sure of the previous version 2.something though

I also have heatmap theme installed, not sure if that matters or not

 

What's located at that (and around that line of code) of plug-in?

 

Login to your file manager and delete the plugin and all files asociated with it.

 

@mccomf

As mentioned he has already deleted the plugin.

 

How do I go about figuring this out?

 

@robaid

Below is the line from Recently downloaded plugin.

 

Well I've pasted the code segment but you can achieve this by opening the plugin folder and then opening the file backup_and_move.php with a text editor.

You will need a text editor which can display the line number otherwise it will be too hard to count and reach that line.

If you are on Windows you can use Notepad++.

 

Thanks to everyone for looking into this. I hope there is a solution in here somewhere.

 

I do not know how this works exactly but can I just define the function home_url() somehow? Any guidance here would be appreciated

 

It doesnt look like the plugin was deleted.Maybe He ment "deactivated".

 

Solved! changed plugins folder to plugins.hold and was able to access admin dashboard


Thanks guys!

 

Ok - I logged in for a minute and then deleted the plugin but now I am having the same exact problem.

 

What else did you do?

 

I didn't really do anything else other than delete the plugin and change plugins.hold back to plugins. I got back into the admin dashboard, left my computer for a few minutes, came back to find that I needed to log back in again and then it looks as if the changes that I made in order to get back to the admin were reverted.

I got back in once again by removing line 149 from the plugins php file but then a few hours later I got the original error and it looks like line 149 is now back in the php file.

 

Did you remove line in backup_and_move.php?
You will have to remove the plugin folder.
Go to wp-content/plugins/ and remove backup-and-move folder.

 

You're doing something terribly wrong but I can't follow the changes you made...

if you deleted the plugin, why is it reporting the same error?
