I used Mynxx since V1.5 and joomla V 1.1.4 VM, and since 2010, most of the bugs encountered in the template has never been supported: the list is long and I had to fend for myself only to debug and modify the code, weeks and days of work .... for someone who is not a developer.
I care to disagree, I have debugged the V1.1.4 VM template version and did a lot of bug fixing.
First one importatn issue to clarify:
SEF URLS is a problem which has NOTHING to do with the template, this is a VM problem alltogether and has never functioned properly in VM 1.1.4. I have posted a number of solutions, handcoding and debugging for members (and I am only a moderator), providing in essence support for VM and not for the template. So the moment you mention that as a template issue, you should read up and get the facts correct.
Now, using a captcha with VM 1.1.4 is another problem entirely, VM did not have its own captcha system, that you wish to use one has nothing to do with the template either.
I would like to see the number of bugs that are according to you unresolved; show me a list.
The only issue I am unsure about is the way in which prices for childproducts are presented, that is the only real possible bug that I am aware of.
I have not told you to update. That is your choice to make, if you wish to run an ancient version of joomla, that does not support the newest developments, then you are free to do as you wish.
By the way, I never get nervous, I prefer clarity. Check all my posts in the Mynx forum, you will find that I posted many solutions, to issues that were not even template problems, but solutions for VM problems.
I have long now abondoned J1.5, but if you need help with template issues, that do not require any custom coding, let me know and I'll take a look.
If you need any type of custom coding, better take a peek in the marketplace
