product descriptions disappear when saving

Hi
I am working with the site (http://combatterror.serightdesigns.com/store)
I am hoping someone can help me. I am trying to update a product - and the admin screens all look find and I can see the product details until I save it and then everything disappears. The product is still there but the description disappears - on both the store side and the admin side.
You can see here what it should look like:
http://combatterror.serightdesigns.c...products_id=41

And what it looks like after I tried to update it:
http://combatterror.serightdesigns.c...products_id=17

I am using v3.9 BUT I tried to update and the database wouldn't update and it was a mess so we had to do a restore. I didn't make any changes to this BEFORE this problem started happening - and it was about 10 days ago.
Any insight would be appreciated. Thanks

This?

I already tried that and nothing happend :/
I am running PHP 5.4.24

v1.3.x is not compatible with PHP 5.4.x

why not?

because 1.3.9 is old, and php 5.4 was under development at the time 1.3.9 was released

would i have to toally upgrade or is there a more simple fix with a legacy version?

The simple fix is to upgrade.
