Tu Tran,

I followed all the instructions of the link provided by you.
Solution 1 – Passed, changed all my folders and archives permissions.
Solution 2 – Passed, it doesn’t have any extensions missing
Solution 3 and 4 – I deleted .htaccess since I’m running nginx and don’t need it
Solution 5 – reinstalled curl

Quickview still not working…

I even reviewed my nginx config files and made some more tweaks, and for me the site is loading a little bit faster, but nothing from quickview. EDIT: And deactivated the minify module, Opti – from Fishpig.

Anything else?

Thanks for effort.
