Hi, I got the below error msg since I restored my Joomla project after I re-installed my OS.
Error displaying the error page: Application Instantiation Error: Table 'joomlabd.nqkpb_session' doesn't existe SQL=DELETE FROM `nqkpb_session` WHERE `time` < '1460104517'
In fact, to Backup my project, I did not use any specific tool, I only use copy/paste of Windows to my USB key.
I copied (www\my_project) that contains my Joomla project,
and to make really sure, I also copied the entire (c:\wamp\) folder to my USB stick too.
After re-installing my OS, I just pasted the folder (\my_project) in (www) of the new OS
and when I opened my web-site via wamp server, I got the above error msg.
I browsed many web forums and they said I was also supposed to backup the db (sql file).
I did not know, so I did not do that.
When I browse my backup located in USB key (F:\wamp\bin\mysql\mysql5.6.17\data\joomlabd\),
I can see all my db files in it.
Like I said, I also did backup of the whole (wamp) folder.
Maybe these db files can help too???
Please can you help !!!
