When debugging zencart online stores, some files are sometimes modified, and the front-end display of online stores is incomplete or a blank page is displayed. You can use the following methods to open the error prompt:
Troubleshooting method for version v1.3.9
Error records in the/Cache/directory, foreground error records file name is "myDebug-xxxxxx.log", background error records file name is "myDebug-adm-xxxxxxx.log"
If you need to display the error information in the browser (note that the customer will also see the error information), perform the following operations:
If a foreground error occurs, open the file \ uplodes \ extra_configures \ enable_error_logging.php.
If a background error occurs, open the file \ admin \ mongodes \ extra_configures \ enable_error_logging.php.
Find @ ini_set ('display _ errors ', 0 );
Change to @ ini_set ('display _ errors ', 1 );
Troubleshooting method for version v1.3.8
Applicable to troubleshooting on the front-end interface
Open the file \ uplodes \ application_top.php and find
If (defined ('strict _ error_reporting ') & strict_error_reporting = true ){
Add a line above
Define ('strict _ error_reporting ', true );
After saving and refresh the page, an error message is displayed.
Modify the preceding statement
Define ('strict _ error_reporting ', false );
You can close the error message.
Applicable to troubleshooting of background interface errors
Open the file \ admin \ mongodes \ application_top.php and find
Error_reporting (e_all &~ E_notice );
Change
@ Ini_set ('display _ errors ', '1 ');
Error_reporting (e_all );
Find the error and modify it back to close the error prompt.

If the above method still does not display an error, please refer to the following post. Thanks to vcboy.

In addition, when there are too many errors
In my opinion
Error_reporting (e_all );
Change
Error_reporting (e_error | e_warning | e_parse );
Better
