Common caching issues #
Authorization and privacy
Disable caching for pages Login, Register, Password Reset, Account, User, Members.
Caching authorization features makes the site unsecure.
Pages Account and User (a profile page) contain private information. This information may be seen for other members if the page is cached.
Members Directory uses a secure request to get members. This request returns 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.
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.
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.
