Can you please server error log and see is there any error there?
Also let me know your wp version, php version and memory limit.
Hi,
thank you for the reply.
Our WordPress version is 5.5.3, PHP version is 7.4.7, and memory limit is 512MB (prob will be extended to 1GB but right now it never crossed 10% of usage).
For server log, it always shows 200 OK but the difference between passed and failed message opening is in response and preview so we do not think it’s a server error and in the message box, we see Refresh this page and try again as a message.
This error shows when there is any ajax error, Normally this happen for server error.
Do you know how to check ajax call in browser developer window?
There are multiple scenarios: if we load a longer message from the start it loads normally, or if we refresh the page when we see Refresh this page and try again as a message it is also loading normally. But when we try to switch between messages we get that problem.
The situation when we loaded shorter message and wanna switch to longer: In the developer console, all messages header is same status code:200 OK with all other parameters looking alright but on messages, it loads we see response and preview, but when we switch to message with longer conversations, Front End Pm does not load Preview: Nothing to preview and Response: This request has no response data available.
Hope it is helpful.
Hi,
managed to find the problem we fixed it by removing WP External Links.
