Back office tabs not working - “Tab does not exist”

[renamed_account_45578]

Hello Great PS Forum!
Thank you for the help in the past. Now it is my turn to post and I would like to resolve this issue ASAP...

Problem:
----------

I logged into Back Office today and for the first time I could not access certain tabs, all the IMPORTANT ones.
The tabs themselves appear but the data beneath them in the white region reads: "Tab does not exist" or is left blank.
This is puzzling since I have not made ANY changes since my last Import, which worked fine. All products display properly in front office!

Investigation:
---------------
The following are the only tabs which, when clicked, DO display the correct forms and data beneath them:

Catalog:
-Attributes and groups
-Attachments

Customers:
-Addresses
-Carts

Orders:
-Delivery slips

Payment:
-Currencies
-Vouchers

Shipping:
-Carriers
-Countries

Stats:
(none!)

Modules:
(none!)

Employees:
-Permissions
-Contacts

Preferences:
(none!)

Tools:
-Aliases
-CMS

The rest are missing. Tools/Import is one of them.


Conclusion:
-------------

I am wondering if there is a simple solution given that some work while others do not?
For example, why do only Aliases and CMS appear? Could this be a token issue?
I have tried using a different login with same results.

Please help ASAP. I cannot find help in the forums and I need some optimism after this giant headache.

But no response. Anyone?

This can occur when Prestashop fails to install or upgrade properly, or your file permissions somehow got changed. Go to Tools > Tabs and check that all the tabs are listed. Click on the Edit button next to a tab that is displaying as "Tab does not exist", then check what is written under "Class". Make sure that this file exists in your admin/tabs directory and it has the right permissions to be read.

Thanks but I

Clicked
* Tools

Clicked
* Tabs

And it reads:

Tab does not exist


The install has been working fine for one year. Front end is perfect. Why this BO issue all of a sudden?

Thanks rocky,

For some reason the remote didn't have all the php's in the admin/tabs folder.

Uploaded and seems to work now.



SOLVED!!!

I wonder if you can help me with my other problem:
