Category or home blank pages.

Hi guys! I'm using 3.0.3.2 Opencart with Journal 3 theme. For 2-3 days i have this issue: Blank page on categories sometimes on home page too. Frist time I discovered that I didn' delete the storage from system folder. I deleted this and restored the storage folder( the one outside public_html) from the server. It works for a while. Now the problem is back again, blank page on categories, I tried to restore storage folder again, it doesn't work anymore. No error in logs. What can I do?

Tried, not working.

Have you checked:
