To query_cache_type or not to query_cache_type

[ChetUbetcha]

1 Windows web server with MySQL 5 and phpMyAdmin.

Two web applications, 2 databases. If I am running Program1 and developing Program2, I start getting errors in Program1 saying "Program2.table does not exist" when I submit forms. I do not have access to my php.ini file, but should there be something changed for query_cache_type or anything else to disable any type of caching?

query alloc block size 8,192
query cache limit 1,048,576
query cache min res unit 4,096
query cache size 0
query cache type ON
query cache wlock invalidate OFF
query prealloc size 8,192

why do you think its a caching issue? does Program2.table exist?

Yes, the tables all exist. You can submit sometimes and it goes the first time. Sometimes you have to submit it 2 or more times before it actually goes. When I was reading up on different settings, I got the impression that the server must be caching some queries and screwing up everyone when they are using different tools. One is using Program1 while I'm developing Program2. They submit to Program1, but get errors about Program2 since I'm developing/using at the same time. And it only happens with 1 of the 3 programs I made.

Is there a way I can search through my code to make sure any and all form submission pages are not using cached info? Or is there a possible setting on that 1 DB that is causing the problems?
