Custom Entity stopped working

[tayling]

HI
I have created a custom entity quite a while ago and have used it successfully to create a record. After not using it for a few months but also not making any changes to fields or layout it is no longer working. It appears on menu etc bit on clicking no form appears. There is no error messages and on checking the logs there are no errors

I have upgraded to version 9 since creating the entity if that is a clue.
Any clues gratefully received.

Thanks in anticipation
Tony

If there is nothing in the EspoCRM logs with Debug mode enabled, then there must be something in your browser console when reproducing this behavior.
