Magento. CMS content is blocked

Is there any error information on the page or in the browser console? Have you recently installed a module?

If a module has been installed, I ask you to create a security testing environment if one is not already present, and disable the installed module to verify that the functionality normalizes, as this may be a conflict. Remembering that to disable a module completely, the best way is going into app / etc / modules / nomedomodulo.xml and renaming the xml. Example: nomedomodulo.xml.disabled

If not, give us more information so we can help you;)
