Problem: Got error “Database tables not found…” after installing Slider Revolution extension.

Reason: Cache was not disabled during installation process.
Solution:
- Go to System > Cache Management of Magento Admin panel 
- Disable All Cache 
- Log out from Magento Admin panel
- Remove nwdthemes_revslider_setup  row from core_resource  table using PhpMyAdmin or by running this MySQL query:DELETE FROM `core_resource` WHERE `code` = 'nwdthemes_revslider_setup'; If you are using tables prefix – it should be DELETE FROM `myprefix_core_resource` WHERE `code` = 'nwdthemes_revslider_setup'; Or alternatively you can download archive with patch file, extract file from it to the root folder of your Magento installation and run it from url: 
 http://yoursiteurl/revsliderfix.php
 where http://yoursiteurl/ is url of your Magento website
- Login to Magento Admin panel
- Enable Cache
