I know it is a free product and i also checked all the other issues that are in this forum. I even tried to solve it myself.
Error: 42S02 SQLSTATE[42S02]: Base table or view not found: 1146 Table 'ellavoge_joomla.xym5j_cmc_lists' doesn't exist
Here is my problem: i get an error that there is no table for cmc available. So i looked and it was true, so i re-installed the product. Still no tables. So i installed it on another website and on that one it was OK.
So now i have copied the tables form the working site to the not working site (with the right prefix). Still not working.
Without the tables there is no way that the register button is going to work.
I see you have this DB issues on more of your extensions. Is there a common way to fix it? or can you help me?
