Hello, I work with joomla verson 1.5.26 and use the version of the component surveys com_communitysurveys_v2.0.12 but upon entering the component tells me that a new update is available that is the com_communitysurveys_v3.0.1 I try to install and gives me error XML.

Any solution?

Also I get the following error

Error: 10304 - You already responded to this survey. If you are seeing this message in error, please contact survey manager / administrator.

And do not like to review the survey and remove this error.


Thank you.
