This is unfortunately a copy of another reply, as the problem and solution is the same:
We can't stop or control this except by asking people to disable the Jomsocial plugins temporarily. Once installed, you can re-enable the plugins.
About 1% of the issues reported aren't Jomsocial, but it the same situation - bad code from an other extension interfering with the Ninjaboard installer.
Our code however is well written as it doesn't interfere with any other extensions. We are always willing to come out to your site and handle the process for you if you like. You only need to ask.
If you want to show the results of your forms, you are even in bigger trouble, because for some strange reason it will display your results in lists instead of tables, which are much more easy to edit.
So, if you want just a form with 1 column, go ahead and use this. But if you want more columns, I suggest a component like RSForm Pro where you can easily edit the tables for every single form.
Hi Each group has a column setting which enables you to render the elements in a series of columns.
The recorded data is shown in a table as the default table template. There is a template which shows the results as a list, but its not the default one.
