Hi,
I am new with virtuemart nad joomla, so please be easy on me.
I am using VM 2.0.20b and Joomla 2.5.11

Suddenly the pdf button has stopped showing the product details in PDF format and shows the information in htm format.
Can anyone please help me out in solving this issue.

I'm not sure what is going wrong. But I could admit that you have too old versions.

    I also admit, that the version are old, but I cannot afford to update the site, as some files are not overrides.
I recently updated my joomla lib files (as was getting Fatal JDate error). Maybe this problem is connected with Joomla library files issue??

VMAIO install own tpcdf library for dealing with pdf files.

I cannot afford to update the site, as some files are not overrides.

DiffMerge or Kdiff programs could help you to document your changes in core files.

this used to work in the current version. but after updating joomla lib files, it stopped working.
For me, updating the versions would be last options, as I have much less time to deliver the project.

Do you really think its coz of old version??

please help me!
thanks

Did you look into libraries folder in VMAIO?

Do you really think its coz of old version??

Don't you think that update must be done NOT on live web site??
