I can’t find 「php error_log」.

I remember seeing this error in very old SuiteCRM versions. Which version are you running?

Thank you for replying.
suitecrm version is 7.12.6
php version is 7.3.14

Delete everything under

cache/themes/SuiteP/modules/Documents

(files will be re-created). Check the logs during that re-creation.

What was the most recent thing you changed, before starting to get this problem?

Thank you for replying.
I 'll try that.

The last change I made was to create a custom field and change the edit view using studio.

I have not changed the source code by my hand.
