When clicking the Donate now button on a Donation form (Mini) part on a donation page, the following error is thrown in all internet browsers. "An error prevented the payment form from opening. Please contact the organization directly to arrange payment."
On the testconfig page, confirm check the RE7 WS - Product Is section to see if it says "RE7 does not recognize that Blackbaud NetCommunity is installed". If RE7 does not recognize that BBNC is installed, correct the plugin service URL in RE > NetCommunity plugin > Options. After correcting that, clear your cache, and try clicking the Donate Now button again on the donation page.
