We have 2 cache versions to propose : Micro-caching with short validity of 5 minutes, and pure caching with validity of 1 day. If you get issues after activating cache like update/displays, follow procedure to get back to default profile 'YOORshop default'.
Change your nginx profile, go in your cpanel, in section 'Nginx', click on 'Nginx-Manager'
Choose first your domain and click 'Configure'
To change profile, see line 'PROXY', you must click 'Select'
Leave httpd, and see dropdown list : 'Temaplte'
Choose for microcache profile : 'YOORshop with microcache', and for 1 day cache 'YOORshop cached', and click 'Update'
If you any encounter problems after cache activation as cache will be updated after several hours only, we won't be able to solve/adjust anything, just revert back and that's all...
Please do not play with other not recommended templates/settings, because they are not set optimally, contact us for any questions
