That's what you assume.We've tried that, but people were choosing that option even if they weren't ready to handle the issues and complexities they ran into, ultimately coming back to us and complaining that it was our fault.
Let me tell you our experience. Our software guy is well experienced with php, js, apache, etc, and he found a solution to the buggy release (the one before the last one) after hours of working on your code. You replied to the ticket 1 day later. Unfortunately I was so naive to upgrade on a live site, thinking that it would work out of the box.
The first time I came in touch with xpress I downloaded and installed the software by myself (been working with forums for nearly 20 years now, even if I'm not a coder), on 3 different websites. Easy, even if not so straightforward as you claim it to be.
So what happened, if WP and XF have been constantly upgraded to their last release? The only variable is this addon.
I've been running Xenword for a long time, and it didn't have 1/10 of the issues, even if it was doing exactly the same thing as xpress.
So maybe you shouldn't complain about your customers being idiots. Just look at the number of issues posted in the last 3 pages in this thread, which all came out of a sudden after the buggy release I was talking about.
