my johncms v4.0.0 problem error

Hallo Admin and moderator. I want to ask, why my wapsite v4.0.0 JohnCMS engine wear is often an error? This address http://muchopick.kilu.de how not always error? I wait in muchopick@gmail.com feedback, thank you.

does your hosting support .htaccess
PS there's no access to your site at primary address, have you finished install?

the installation process I had been going through. I admit, maybe too much wear on the modification module. Is it true that the problem is. Htaccess? In the folder where? I use a hosting a pretty reliable, although I admit, hosting is free.

he installation process I had been going through.

Were there any mistakes during the process of the installation?

maybe too much wear on the modification module

If there is no useful data, reinstall the whole site using only files from distributive (no additional mods and hacks)

Htaccess? In the folder where?

In the root of your site

I use a hosting a pretty reliable, although I admit, hosting is free

Ask support of the hosting weather have they support of the .htaccess or not (do it first of all)

The installation process went perfectly. but when I replace the original file by file modifications, eg index.php in dir / www, I often wapsite error. I have a plan to update the version to 4.4.0, what should I do? I can only use the support of this temporary cell phone. how to backup all data wapsite how? of the number of members that nearly 250 people, attack files and topics in the forum, also download files in dir.

sometimes it is not enough to replace the files, run the installation process

So what should I do? do I have to give up data wapsite already pretty much lost if I do an update version?
