The message of "Page not found" on the homepage

[SWSUSA]

Hi! The homepage of the forum http://glbyh.ru ceased to open. Writes: "Page not found". Though other http://glbyh.ru/showthread.php?t=18811 open. In what there can be a reason?

Привет! Главная страница форума http://glbyh.ru перестала открываться. Пишет: "Page not found". Хотя другие страницы http://glbyh.ru/showthread.php?t=18811 открываются. В чём может быть причина?

Faulty plugin installed? Got hacked perhaps?

[SWSUSA]

I enter the administrator's panel. The site isn't hacked.)

В панель администратора я вхожу. Сайт не взломан.)

check your index.* file(s) to make sure they have not been changed
From ACP run the Suspect File check (ACP->Maintenance->Diagnostics->Suspect File Versions)

[RichieBoy67]

This just happened or did you do anything first? Server move or something?

I checked. Writes:
forum.php the File isn't part of vBulletin
index.php the File doesn't contain the expected contents

Проверил. Пишет:
forum.php Файл не является частью vBulletin
index.php Файл не содержит ожидаемого содержимого

It occurred in itself. The site normally worked the last months and I didn't do any changes at a forum and on a hosting.

Это произошло само по себе. Сайт нормально работал последние месяцы и я никаких изменений не делал на форуме и на хостинге.

then your forum.php and index.php were either hacked, or corrupted. Upload fresh copies of both

I replaced files on new, writes too most.
forum.php the File isn't part of vBulletin
index.php the File doesn't contain the expected contents

Я заменил файлы на новые, пишет тоже самое.
forum.php Файл не является частью vBulletin
index.php Файл не содержит ожидаемого содержимого

it seems you might have been hacked. You might try reuploading all the vb files and running the upgrade script.

I will try to load a backup. Truth it 3-month prescription.

Я попробую загрузить бэкап. Правда он 3-х месячной давности.

I loaded a backup. Helped nothing.

Загрузил бэкап. Ничего не помогло.

So even when you upload the original forum.php and index.php file, the same problem is happening?
Definitely a bad plugin/hook or .htaccess file.

[SWSUSA]

Yes. Да.

Definitely a bad plugin/hook or .htaccess file.

I assume that it because of settings of the web server or because of one of the established spendthrifts.

Я предполагаю, что это из-за настроек веб-сервера или из-за одного из установленных модов.

I solved a problem. It because of a code in the .htaccess file.
With such code the site ceased to open:

Решил проблему. Это из-за кода в файле .htaccess.
С таким кодом сайт перестал открываться:

With such code the site opens:

The part of this code is necessary for fashion [DBTech] of DragonByte SEO v2 (vB4). Though itself fashions at me it is switched off.
Часть этого кода нужна для мода [DBTech] DragonByte SEO v2 (vB4). Хотя сам мод у меня выключен.

The part of this code optimizes a forum, increasing the speed of loading of pages.

glad you got it figured out, but did you not tell us that you didn't make any changes, it just suddenly started happening? If you had told us about the changes made to .htaccess we could have figured it out sooner ;)

I did changes in the .htaccess file 5 months ago.
Изменения в файле .htaccess я делал 5 месяцев назад.

I think that the company the owner of a hosting made some changes on a hosting though they also won't confess in it. I saw on a hosting there were new functions and new folders, just that day when my site ceased to open. And this code in the .htaccess file ceased to work normally.
Я думаю, что компания владелец хостинга внесла какие-то изменения на хостинге, хотя они и не сознаются в этом. Я видел на хостинге появились новые функции и новые папки, как раз в тот день, когда мой сайт перестал открываться. И этот код в файле .htaccess перестал нормально работать.

ahh ok, I would open a ticket to your host and ask them what changes they made recently then. They might have upgraded PHP or Apache, but it would be handy for you to know what they are doing ;)
