Debugging & problem solving

Your code should not produce any PHP warnings or notices during normal usage. This primarily implies that all variables must be defined before being used. It also implies that a corrupted installation may produce errors, although as far as practicable the code should accommodate this.
By default, all PHP errors, warnings and notices are suppressed and not visible to the public. You can use debugging to show them.
A blank page or a page that has not been fully loaded, usually indicates a PHP fatal error. Server logs (such as Apache Error Logs) often also provide useful information.
We recommend this collection of Firefox Addons. The most important being the e107 Debugger. If you don't wish to use the debugger, you can still activate various debugging modes manually, by changing the query string of the URL and adding the debug mode. For example: directly after .php add ?[debug=xxxx]
Example: yourwebsite.com/news.php?[debug=basic!]
[debug=basic!]
Display basic error information
[debug=traffic!]
Display traffic information
[debug=showsql!]
Display basic SQL queries
[debug=time!]
Display load/processing times
[debug=notice!]
Display PHP Notices
[debug=warn!]

[debug=backtrace!]

As of e107 v2.3.1 - the + sign has been changed to an exclamation mark !.
For example: [debug=basic!] instead of [debug=basic+]
