Hello,
I have a new install of Hikashop running on Joomla 2.5.6. Everything appeared to be working fine until I installed Community builder.
When I enable their login and disable Joomla's login, I get a 500 error when I try to go to the checkout page when logged in.
I have downloaded and installed your plugin as described in the online docs and enabled it in CB. I enabled the tab in CB. The only other thing i saw in your docs was to be sure and enable the Hikashop plugin, however I have searched the installed plugins for Hikashop and there does not appear to be a plugin for Community builder other than the one installed in Community builder.
When I dissable all links from Hikashop and CB, it all starts to work again.
Any suggestions?
