Multiple controls with the same ID error - Sitefinity - General Discussions

I have a local version of Sitefinity 6.1 so I can develop a custom payment processor plugin. It was working just fine until I tried to edit a product yesterday and I got this error:

Multiple controls with the same ID 'ecommrcPrdctsCntView$productsBackendMaster$ctl00$ctl00$sidebar$languages' were found. Trace requires that controls have unique IDs.

I have no idea what caused this error. Can someone help me figure out how to fix this or what is causing this so I can fix it in the future?

Trace:
[HttpException (0x80004005): Multiple controls with the same ID 'ecommrcPrdctsCntView$productsBackendMaster$ctl00$ctl00$sidebar$languages' were found. Trace requires that controls have unique IDs.]

Hi,

Thank you for contacting us.

We have encountered a similar problem before, which was caused by enabled trace logging in the web.config file. Would it be possible to check if you have that enabled and if you do, remove the following lines from your web.config:

<system.web>

<trace enabled="true" …

Thank you in advance.

Hey Atanas,

That was the problem. Thanks for the suggestion.

How do I trace any custom modules in sitefinity? I'm new to ASP.net and can't quite figure it out. For debugging I have just been throwing exceptions and reading whatever I output in VisualStudio. Is there a better way of doing this that wont stop the execution?
