Caching problems
Common caching issues #
Authorization and privacy
Caching may influence authorization features such as the Login, Register, Password Reset pages and make them broken or unsecure.
Pages Account and User (a profile page) contain private information. This information may be seen for other members if the page is cached.
The Members page contains a member directory that uses a secure request to get members. This request may return an error if the page is cached.
Content restriction and redirects
The cache can save a page for one user and then display a saved page for other users. That's why content restriction and redirects may work wrong on cached pages. Please disable caching for pages that use the content restriction feature.
Multiple caching
Using multiple caching plugins is a bad practice. All caching plugins are unsafe and may break layout or functionality. Using multiple caching increases the risk of error many times. Please select one caching plugin you want to use and deactivate other caching plugins.
Hosting caching
Some hosting providers have a built-in caching tool on the server-side. In this case, you have to contact hosting support and ask them to exclude certain pages from caching.
How to disable page caching #
Please disable caching for pages Login, Register, Password Reset, Account, User. Disable caching for the page Members if it works wrong on your site.
