Pages protected by the plugin are not displayed

Hello
Our site used your plugin to create a subscription plan. For several months, everything worked correctly. We recently found that the pages are not displayed, only the title is displayed, without text and images. If you pick up the link to the subscription plan on the page, everything works fine. We have already reinstalled the plugin and updated, nothing helped. This may be due to an automatic update of the WordPress version. we do not want to replace your plugin, so we will be happy to help thank you for your attention
