Seeking Assistance: Custom Buttons Not Functional After SuiteCRM Update

Hello everyone, I hope someone could help me with an issue I’ve encountered after updating my SuiteCRM platform from version 7.12.7 to version 7.14.3. Since the update, all the buttons I display via custom code in my detailviewdefs.php are no longer functioning. Does anyone know if there are any specific adjustments that need to be made to get them working correctly after the update? Thanks in advance!

Check if you still have that code in your SuiteCRM directory.

Thank you for your feedback. Yes, the code is indeed present in the SuiteCRM directory. However, I noticed that all custom buttons have disappeared, even the custom codes from standard modules are no longer displayed. This is the case in both the reports and meetings modules
