[SOLVED] lost tabs in BO

[michal123]

Hi,

I updated PRESTA from 1.2.5 to 1.3.1.1. (instalation version of 1.3.1.1., only modules and themes from my old 1.2.5).
In FO all works good, in BO no errors, but... My problem is, that in BO tabs" "DB backup" and "Attributes and groups" are empty. After click, I get "Tab does not exist".

What can I add to my folders, what I lost? It is hard to find it, because in url I get some dynamic generated adress with token.

I would preffer to repair my version of PS, without reinstall all working good, so I hope it is only matter of wrong conection, or folders etc.

Thanks in advance!


SOLVED!

Check in admin/tabs/ do you have proprety files. My files "DB backup" and "Attributes and groups" were empty, and has 0 KB.
To solve, replace this files from installer.
