Parse errors happen when the code doesn't conform to the syntax or language rules for the language in which you're script is working. In Oxwall, parse error is known to be caused by third party plugins and custom code( javascript in particular) added to Custom HTML widgets.

This documentation uses Firebug as a debug tool. Alternatively you can use native debugger that comes with Google Chrome.

To find out which plugin/piece of code is causing parse error:

• Open the page where parse error happens in Firefox.
• Enable Firebug.
• Choose Console >All in Firebug's panel.

• Reproduce parse error message. Example: if you get parse error when signin in, then sign in.
• Once parse error is reproduced, find parse error entry in Firebug's error log. Pay attention to the action script tried to execute before the parse error message.

• Open details of this action using “+“sign »navigate to “Response” section. Here you will see detailed information on what went wrong. Read the response carefully, look for the file/function names.

In this example “Groups” plugin caused the parse error since GROUPS_BOL_SERVICE - is the class that belongs to this plugin.
