I am absolutely sure, that I didn't change anything in backend code. My backend is called "admin". If I write on my localhost localhost/admin, I get "This page is not available" in my chrome. But the frontend works well. What can be the problem? Yesterday I installed any plugins. Can be that a problem?

//edit:

I look at error log. There something like this

[2015-03-20 22:05:35] production.ERROR: exception 'PDOException' with message 'SQLSTATE[HY000] [2002] Nedalo sa vytvori žiadne spojenie, pretože cieľový počítač ho aktívne odmietol. * ' in C:\wamp\www\octobercms\vendor\laravel\framework\src\Illuminate\Database\Connectors\Connector.php:47

Check your database settings first. If that is not your problem...

How did you change the backend url to admin? Did you change anything else at the same time?

I changed backend url during installation, You can set backend at your own there in settings. I think that's not a database problem, cause frontend works well... I didn't change anything, as I remember. Last activity I remember from yesterday - I click in settings->maintenance mode. After that click it died

Front end does not use the db unless you have added plugins.

I have got blog posts there and they are working well... They are stored in database, aren't they? I don't know what to do now. Should I try new install direct on free hosting and copy there a project? Or what should I do? I used google too, but nothing, what I found, help me... :(

I think it's because of that maintenance mode. How can I disable it? I looked at database, but nothing I found there...

OK so your front end is displaying blog posts ok, so that means your db connection is ok. The next most likely thing is that there is a plugin that is causing the problem. If you cant access the backend, you have no choice but to disable them manually. One way to do this is to edit system_plugin_versions database file. You could try just removing the files temporarily. Somehow you need to get to your backend...!

I have there

• RainLab Blog
• RainLab User
• RainLab Sitemap
• RainLab Alxy.Simplemenu

I used there plugins before are here wasn't a problem. So I think, it could be a sitemap plugin... I am justi trying to remove it and we will see ;)

OK, so I just delete all the ROOT/plugins folder and delete all rows in DB in table: system_plugin_versions and still doesn't work :(

New installation next! Then copy theme folder and each plugin and test at each step.

Can you recommend me any free hosting? I just tried to install it on endora.cz, but it always gives 500 internal server error. That freehosting sucks...

Did you customize your backend layout?

Yes, I tried something to customize... but I don't remember, if I also saved changes. I also add a widget into backend homepage

I just delete all rows from table system_settings, but still doesn't work

I tried to customize backend via settings in another project and there's the problem. So you are able to edit your backend, but you mustn't do it... WTF? It's beacuse of October is in BETA?

Holy cow! From 6:30 a.m. to 3:18 p.m. I was trying to repair this bug... Dafuq?

I got the same problem when I customize my backend.

Maybe if you delete your cache it will work again.
