I have movie managment post type and I have many post select meta field (40-50 field) that post types have 100+ posts. For this reason, the page loads very slowly and sometimes crashes. Is there a solution?
There are some potential issues that increase the loading time or break the page. Mostly, it is the hosting is not powerful enough to respond to all browser requests at the same time. You can try to use a few post fields and re-check the issue. If the loading time is good, you can contact the hosting support to ask for help with this issue.
