After upgrade : 3 categories "timed out"

[django29]

Hello
I was so happy that my website with Virtuemart was upgraded to the last versions, Joomla 2.5.9 and VM 2.0.18a ... the same for the template and extensions (a lot of work).
1and1 shared hosting.

BUT, now 3 of the sub-categories are not displayed anymore. The navigator turns during 1 or 2 mn, and .... white page.
The logs say "Timed out"
All the pictures are optimized.

So why a problem only on these 3 sub-categories ? If somebody could help me ... in english or french ...

you may post your page, or even better the link to the subcategories
