I have a major problem, maybe my pages got sabotaged even. I walked out of work one day with a full php app working came back two days later and its not working, if you hit for example "view order" it just goes to a blank page or logs you out, I have spent a week trying to find the problem with no luck at all, I don't understand what happened over last weekend, and this work order system is thousands upon thousands of lines of code, which WORKED perfectly as of Nov 13 but by the 17th it was hosed...any ideas how this can happen..code is code right it doesn't change unless its been tampered with and now I'm searching for a needle in the haystack here and my job could be on the line YIKES....help please, the pages are big but I would be happy to email the code to someone that could help, I have gone in the db and checked for not null fields even set them all to be ok with null still nothing....
