[parfumylacno]

Hi all,

I have Joomla! 2.5.25, i dont remeber any changes on web in last days (only edit one old article, but then web was still working, and I had only made some changes with order statuses in virtuemart = that was yesterday evening and web was working) and from today morning i can only login to administration, but when i click on any icon ( virtuemart, product, orders, or even create new article...) then error shows (only in administration, web is working for now)

500 - Došlo k chybe.

JHtmlGrid: :sort file not found.

Back to control panel

I write to hosting - They told me that it is probably should be problem caused of some automatical update (i dont know about any)
they found me in error log many errors from yesterday evening: to example first od that is:

JHtmlGrid: :sort file not found is often associated with a failed or corrupt Joomla update which you say you have not done. However, Joomla 2.5.25 has critical security issues which have been known about for about a year, so you should consider hacking to be a possibility.  http://forum.virtuemart.net/index.php?topic=118683.0

The PHP warning is coming from yout VM2 cart plugin, not part of default VirtueMart, and in any case, warnings can be turned off.  http://forum.virtuemart.net/index.php?topic=102555.0

shloud help for now recover web from back up on FTP hosting?

how would we know this?  Consult with your host etc etc if u have made no current backups

[parfumylacno]

You have right, you have no chance to know if i have current backup - luckily i have one and backup was succesfull, parfumylacno is now working.

Is there anything to do with this issue and for prevention - can i found by some way what have caused  this problem? If it was really hack? I think that there is no way to found it out what caused this problem, but for sure, i ask if anyone had simillar expirience..

i know that best way would be update to newest Joomla, but for now i can t update, so i will see .....

thanks a lot for your help, thank you
have a nice day

[jenkinhill]

Problem is, that if it was a hack, you are highly likely to get hacked again very soon now that your old version has been found!

At the very least update Joomla to 2.5.27 and apply the remote code execution security patch.  https://docs.joomla.org/Security_hotfixes_for_Joomla_EOL_versions

thank you very much! i had manually add the sesion.php and debug.php files from Session Hardening Patch to correct places via ftp
