Last November I upgraded from 1.3.8 to 1.5.5 and it's been one thing after another. Now for the last two weeks my site keeps knocking out my hosts server and he has no clue why. At this very moment I have Database Error 0071 and can't access the database. And all sites hosted by him are down and it's my zencart that's doing this. I can access ftp though so nothing wrong with files. I've triggered this several times now by editing an order to mark shipped or editing a product using the admin panel. Also triggered one time when I went to log into phpmyadmin.
Once he resets Apache (I think that's what he's doing) the site then works again for a while until something (and he doesn't know what) knocks it out again. Anyone have any clue what's up here? He said he thought if I could use php 7 it would fix it but my Zen apparently won't work with that because some of the plugins I use often won't work with 7. I've asked him constantly if the logs say anything and he never answers so they apparently don't say anything or hes missing the problem. I don't know much about this stuff but if you have anything helpful I can relay to him that's appreciated much!
