Upgrading PHP, zc installation not working

My host upgraded PHP from 5.3.28 to 5.5.9-1ubuntu4.14. After that the zencart 1.5.3 version doesn't work. When trying to enter the shop, I get the installation page ('Hello. Thank you for loading Zen Cart, etc '). If I try to run zc_install/index.php I get 'Not Found. The requested URL /nettbutikk153/zc_install/index.php was not found on this server.' Get the same page when trying to log into admin. The whole 1.5.3 installation is on the server. Also zc_install/index.php.

Everything else on the server is working all right (wordpress, webtrees, mediawiki, mysql databases). Only zencart stopped working.

Any tips on how to fix it? Or should I start a fresh installation of 1.5.4?

it seems there is an apache configuration issue going on.

i would look at what the host has your base apache configuration and compare that to what is in your includes/configure.php file.

upgrading PHP should not break your site in the manner you describe. it sounds like the configuration has changed which warrants a change in the above file.

good luck!

Thanks for your answer.
I'll check with the host on monday and report back

Also a llttle confused about the current condition. Does the directory zc_install exist on the server off of the store's base folder? What happens if you remove it like is suggested in the installation instructions?

As mc12345678 indicates, the zc_install directory is normally renamed prior to your site going live so it's not surprising that /zc_install/index.php isn't found on an up-and-running store.

That's a red-herring, though, as there's text buried in the message you received that indicates what issue was discovered when your store tried to start.

My host has sorted everything out, they were changing servers while uppgrading PHP. Everything is working OK now.
Thanks for everybodys help.
