WordPress 5.7.2 Siteground SG Optimizer Plugin 5.7.20
Nginx Direct delivery on, Dynamic Cache on, memcached all sites off. Cloudflare Basic level.
We are having the same issue with old page content being cached and new page edits not displaying for end users.
Confirmed adding a query string to the end of the url (e.g. ?test=1 ) results in new page content displaying in browser correctly so page has been updated.
Rechecking normal url without extra test query string and clearing browser cache and refreshing page results in old content being displayed again.
Clicking on Purge SG Cache
link or wp-admin menu > SG Optimizer > SuperCacher settings > Dynamic Caching > Manual Cache Purge > Purge Cache
results in message “Dynamic Cache Successfully Purged”. However reloading page still displays old content.
Automatic Cache Purge is on.
Visting Siteground Account > Site Tools > Speed > Caching > Dynamic Cache > subdomain > Actions: icon for Flush Cache and clicking the sweep icon reports “Success: Cache for subdomain.domain.org.nz flushed”.
Simple refresh of page displays new content.
Contacting Siteground support – they recommended using Siteground account flush through Site Tools only when needed – which is after every page edit! Not practical for a multisite wordpress install.
It appears in our case, with a multisite wordpress install on a subdomain within the main account with a wordpress install on the main domain, the Plugin “cache purge” and “auto cache purge” are not working. SG Optimizer is installed on both the domain website and the subdomain multisite.
The work around we have been forced to use is disabling Siteground “Dynamic Caching” by turning it off in the plugin. On doing this old content is still delivered. After disabling going into Siteground Site Tools and flushing one final time results in changes being shown instantly after each edit.
