How is it vague if I clearly explained it and told what exactly I want to be done I don't have a problem giving my FTP but if you know how to do it then you can just tell me and I will figure it out myself just like the last thing Sasha told me to do...
sometimes its not as easy as saying i know how to do it? as an example, if you take your car to the automotive shop for repairs. yes they can fix it, but no they cannot tell you what to do just by you driving up and saying my car is in need of repair. there is more to it than what is presented verbally.
there is a reason something has gonna askew on your site, as that is not a default behavior, so whatever action you had taken to create the situation, you would need to back that out, and start over, in hopes of circumventing the error from replicating. also there are error logs, so even though you are being presented with a 'blank' page, which essentially there is a parse error, and php is unable to interpret the files that are being called, there are somewhere, hints and clues as to what needs to be modified.
do we know exactly which file, or possibly which database table? no, was this the only thing you done to the site, we are uncertain of the exact interaction you had with the site, so to say oh just go click on this and change that, would be ludicrous as an expectation.
but good luck in your ventures.
