several problems

Hi to all,

since I have changed to 3.2.1 started to have some problems.

first one was:
add an image >> set that as thumbnail >> click on insert to post … in editor everything looks perfect, click on view page… this is the result:
http://insects.nature4stock.com/?page_id=817

the only way to solve this is that “artificially” insert in code the line “[gallery link="file"]“

the code inside was the same as in page that was previously edited and works also now. but if I try to edit that page (only to resave) everything is “destroyed” also there

second problem and the biggest is… last night worked a lot again inserting new pages and after redone indexes even if all looked well in editor when saved and seen the pages all was messed up.

missing lines, different editing… this problem more exactly at this addresses:
http://insects.nature4stock.com/?page_id=75
http://insects.nature4stock.com/?page_id=12

I have tryed to change the “theme” to see if it is theme related but was the same on WP clasic and WP default. I don’t know how to install another version of WP to go at a previous version (that worked well).

this can be solved in any way?
thank you very much,
cosmln
