!JoomlaComment 2.40 is probably the best free commenting component available for Joomla content management system (CMS). Unfortunately, that may not be good enough for those Joomla developers or web site owners without a lot of coding, troubleshooting and hacking experience, because it is pretty buggy.
First of all, if you aren’t using Community Builder, you are going to get the following error when you try to use this component:
joscomment Warning: Invalid argument supplied for foreach()
It’s an easy enough fix, if you are comfortable commenting out some code. The instructions can be found here: http://www.haanchiang.com/joomla-comment . Also available on that page is a downloadable version of the component with that and a couple of other patches already installed. I installed the haanchiang version right after I got the first error, so didn’t have to deal with the other errors described on the page.
After that was solved, I set the admin to allow anyone to post, but required that the posts be approved before publishing. When filling out the comment form and hitting send, I got the following error:
Database error: insertNewPost!
The post, however was inserted into the database and I could publish it just fine. More than just an annoyance, however, because the user would tend to think the post wasn’t accepted, and may try again. Because I haven’t been able to fix it, I have no choice but to remove !JoomlaComment from my Joomla installation. In searching for a solution, however, I did find a lot of posts about various other bugs that people are experiencing with this component. If this is version 2.4, I’d recommend waiting for 9.2 before giving this component a try.
