1. It may be helpful to know if there are any errors logged:
   1. in the Espo log in data/logs directory;
   2. in the web server error log;

The data logs display the following information:

I have modified the permissions for the folders custom/Espo/Custom using the following command:

sudo chmod -R 777 custom/Espo/Custom/

The issue has been resolved, and everything is functioning correctly now. Thank you for your help.
