Production Issue in BackOffice cannot Open throws 404 Error

[yashman]

Hi,

 

Until 2 days ago my PS 1.6.11 backoffice was working perfectly but suddenly today I cannot open it at all and it throws 404 Error. There are no changes done in URL, Admin Folder name, and AutoUpgrade is disabled.

 

The Front End URL i.e., http://www.greatonlinesale.sg is working fine but not the backend.

 

I need the solution urgently as it is a Live Instance.

 

UPDATE:

 

I tried to find some issues using the below steps

 

1) Enabled Prestashop Debug

2) Now the page shows the below error. I remember recently there was the blockuser module upgrade and I believe there was some issue in it.

 

Now can you please share how to fix this issue. Sorry I am not a technical person, so please bear with me.

Notice: Undefined variable: current_user in /home/greatonlinesale/modules/blockuserinfo/blockuserinfo.php on line 63

Appreciate early response.

ok, first, you can remove the blockuser info to get the back office working.

second, reupload the adminfolder with other name, and try to access.

you can reupload the blockuserinfo too module

Don rule out provider issue, I had the exact same problem today. I called the provider and it had to do with a php version that was being called for on their end and it was fixed within two minutes of calling. I had to do nothing
