Product description breaks after too much html cod

Hello,

I have a joomla site with virtuemart, using eCommerce template. Im using product description with its WYSIWYG editor to make color chart and its huge. After a certain amount of html code (its all <table>) it doesnt work anymore and it breaks the site. It kinda just takes the lower part of the site and puts it in... We tried to set the limit of character in mysql way up, we put product_desc to mediumtext (also longtext) type, but it didnt work.

problem is on the remnait of tabs on the right side, title "Barvna karta".

Thanks

That is not our area of handling problems. Probably you can find help on editor vendor forum. You can also try to use some other editor. Popular are JCE and FCK
