Same problem
I'm having the same problem installing Fabrik 2.0, however I can still install other components, plugins, and modules without any problems. I've tried installing from the 2.0b download, and I've downloaded the svn and tried to make my own installer zip file using the instructions on the SVN page, and instructions I found here in the forum. I think the SVN is the one I should use however the "making your own install zip" doesn't seem to have a complete set of instructions anywhere. For example The main instructions say:
To install the exported SVN files as a component form scratch,
create a new folder called "com_fabrik" and copy into this the
files found in "administrator/components/com_fabrik" and
"components/com_fabrik". Make a zip out of the com_fabrik
folder and install this as a new component.
Following the above instructions as I understand them means that there are duplicate files from these two folders that will overwrite whichever folder/files you copy first.
When I tried to use the other instructions I found, it said to just copy the xml file out to root of the zip file I was going to make and then zip the entire contents of the svn download.
Neither of the instructions have given me a successful install, and both create errors similar to the errors in this thread.
Thank you for any assistance you can give me.
