my website ran in good health for around five months now. it had average 20 people online and site was very popular among my facebook friends. but during last two weeks i had to face a "500 Internal server Error". so i complained to the host and they repeatedly point me i have errors in my script that consume more memory. so they ask me to fix my scripts. so we tried for three days to get our scripts confirmed and update them and all. but unfortunately reasoning that same 500 error we messed up our scripts and the database. so at last we asked the host to restore to a month early backup where no errors exist. so they did that, but the same errors were started to come. so it proves my scripts were not bad and there should be something with the server. but during the revert we lost most good content of the site. so after all these webhost finally sent me this reply... so as they say i have a memory limit of 500MB .. i don't know why the site suddenly started to hit that.. and i find no need of a reason to move to a vps. to me this is kind of a host trick to pull me off. they might intentionally creating this situation. and asking me to leave. just because my site is little bit active. so i have invest a lot amount of money i had, to start this on. so now in a totally LOST situation. so if you can help me on this that would be much appreciated. Thanks.
