Hello... Soryy how can i clear cache? Have I to use any plugin or is there some function in CMS admin panel ? Thank you  (OsClass version "3.7" theme "Zara")
Thanks for help

And one more question in my site was saved (i don't know how) some information in BO (backoffice) plugin how can i delete it (see screenshot). I delete it manualy every time when i publish some listing but in next time it present again...


Thank you one more time

- theme does not use any cache system, you may have some plugin or your hosting does it
- you have these settings in oc-admin > Backoffice Manager Plugin > Listings > Form Hook Settings
