G'day, PAUSIMS. As you know, support for K 1.5 is extremely limited. In general terms the best advice that I can give you at this time is to read
Before you ask for help with template issues ...
One of the biggest problems that affected K 1.5 users was templates. People would use templates of their own design that were developed for one version of Kunena and, when they upgraded K 1.5, they would not re-apply the changes they'd made to their templates. Another problem was that many people remained "stuck" or fixated on outdated templates - templates that the developers knew were defective but that would have entailed huge investments of time to fix - and, in spite of all the warnings, people still refused to take the advice and use only the
default_ex template. Therefore, the next piece of advice is to read
There is only one endorsed and supported Kunena template ... default_ex
.
Lastly, the current focus of the
Kunena project team is firmly set on building K 2.0. This next version builds on the advances made with K 1.6 and extends them further. As you would imagine, K 1.6 has made K 1.5 obsolete (in much the same way as Joomla 1.5 made J! 1.0 obsolete, too). Web software changes so quickly (and is so cheap) that most people are early adopters of new technology. Web technology is disposable technology - it's not really worth the trouble, most of the time, trying to fix things that are broken when it's easier, quicker and cheaper to throw it away and start again.
We encourage people to use K 1.6. We cannot always guarantee that we will be able to solve (or even attempt to solve) K 1.5 issues. For example, I have one K 1.5 test site - I keep it for "sentimental reasons" - but with 50 or 60 questions being asked every day about K 1.6 I don't have enough time these days to look too deeply at K 1.5 problems.
Although I mainly use
Firefox, I do have a copy of
Internet Explorer 8 and
Google Chrome installed on my PC for the occasional browser-specific problem. I'm certainly no expert when it comes to understanding the peculiar issues associated with
Internet Explorer.
In summary, everyone is entitled to make certain choices with how they design their websites. However, every choice you make incurs a cost. If you really believe that your choice is the best one then you have to accept that there may be times when you won't be able to solve everything yourself ... and you might have to pay an expert consultant to fix those problems for you. So you must ask yourself whether you're prepared to wait, while someone else fixes something that you know will always be "second best", or bite the bullet now and replace it completely.
Those are my personal suggestions ... for what they're worth. I hope there's something that is helpful to you.
