Help me please.
After the last update from version 12 to version 14.0.5, the interface broke and when trying to enter Settings - Modules / applications, an error is issued: “Fatal error: Uncaught Error: Undefined constant” warning "in … / httpd.www / db / htdocs / core / lib / admin.lib.php: 655 Stack trace: # 0 … / httpd.www / db / htdocs / admin / modules.php (501): modules_prepare_head (1, 75) # 1 {main} thrown in … / httpd.www / db / htdocs / core / lib / admin.lib.php on line 655 "
As far as I understand, some modules were disabled, which caused problems in the kernel. Only basic modules were used.
How can you return Dolibarr to its original state without losing the accumulated data? Completely deleting files from the server and installing a new version with a connection to the existing database did not help, the same fatal error.
