V1.7 Conflict with 'Electron Mega Electronic Super Store' and 'Super Speed'

[moonfire]

I had the module 'Super Speed - Incredibly fast - GTmetrix optimization' installed on a shop, then I installed the theme 'Electron Mega Electronic Super Store'.
When I activated the theme, Super Speed became messed up. There is probably some kind of conflict with a css or js-file. I just cant find what is causing the error.

Does anyone have any idea of how to fix this conflict?

1. uninstall ets_super speed in backofiice
2. delete folder ftp /modules/ets_superspeed
3. delete all tables in mysql database - ps_ets_superspeed
4. clear all cache
5. check 1 hour ( delete server cache )
6. install last version ets-super-speed
