Behind a suggestion that was given to me here in the forum, I installed "something" (not sure if the extension or form or whatever) that allows me to divide the product description in multiple tabs with the commands {tab} = XXXXXXX. Unfortunately, if the descriptions are too long truncated me the last card and is then outside a SPAM in the display on the site, all broken ... how can I fix it? I also have a limit of three cards, but I can service up to a maximum of five, and the text (usually tables) must be longer than now. If you need I can post a link to a sample product.
Use Virtuemart 2.2 and Joomla! 2.5.8 Stable I would not do the upgrade because everything, apart from that, it works fine for a couple of years
Probably better if you talk to the provider of the "something"
