Ошибки, не пускает в админку

[faq2013]

Дорогие друзья, кто может тот поможет. Кто не понял тот поймет  

Проблема в следующем, был сайт работал себе и его перенесли на другой впс. На впс стоит вестацп и она пишет кучу логов с ошибками, ошибки приведу ниже. Эти ошибки и возможно что-то еще забивают диск на серве и падает все, в весту не зайти, в пма тоже.
Вот лог ошибок, особенно время, за секунду сколько вылетает и забивает диск.

После того как освободил место, все стало на места. Но проблема которая раньше была в ПМА (логин пароль вел, а не входит, просто обновляет страницу) перекочевала в админку сайта, и ты просто нажимаешь кнопку стр обновляется но ничего не происходит

Slow network is detected. Fallback font will be used while loading
вот такая штука есть в консоле браузера на странице входа в админку

Всем здравствуйте! Дабы не захломлять форум, напишу в этой теме. Проблема та же, не могу попасть в админку опенкарт. (окстор 2.3). Скачивал с сайта ocstore.com. При вводе пары: логин/пароль происходит переход на https://adverts-site.000webhostapp.com/admin/index.php?route=common/login&token=3JRFZD81fBWFjJ6EmUbQBYhFi57qojqz

При этом ни каких ошибок не выдает.

Файлы config.php и admin/config.php переименовал. 

Пара 

define('DB_USERNAME')
define('DB_PASSWORD')

в обоих конфигах совпадает.

Cache чист.

.htaccess

# 1.To use URL Alias you need to be running apache with mod_rewrite enabled.

# 2. In your opencart directory rename htaccess.txt to .htaccess.

# For any support issues please visit: http://www.opencart.com

# Prevent Directoy listing
Options -Indexes

# Prevent Direct Access to files

## For apache 2.2 and older, replace "Require all denied" with these two lines :
# Order deny,allow
# Deny from all
</FilesMatch>

# SEO URL Settings

# If your opencart installation does not run on the main web folder make sure you folder it does run in ie. / becomes /shop/

### Additional Settings that may need to be enabled for some servers
### Uncomment the commands by removing the # sign in front of it.
### If you get an "Internal Server Error 500" after enabling any of the following settings, restore the # as this means your host doesn't allow that.

# 1. If your cart only allows you to add one item at a time, it is possible register_globals is on. This may work to disable it:
# php_flag register_globals off

# 2. If your cart has magic quotes enabled, This may work to disable it:
# php_flag magic_quotes_gpc Off

# 3. Set max upload file size. Most hosts will limit this and not allow it to be overridden but you can try
# php_value upload_max_filesize 999M

# 4. set max post size. uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields
# php_value post_max_size 999M

# 5. set max time script can take. uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields
# php_value max_execution_time 200

# 6. set max time for input to be recieved. Uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields
# php_value max_input_time 200

# 7. disable open_basedir limitations
# php_admin_value open_basedir none

### Display PHP errors 
### Uncomment the commands by removing the # sign in front of it.
# php_flag display_startup_errors on
# php_flag display_errors on
# php_flag html_errors on
# php_flag track_errors on
# php_value error_reporting "E_ALL"

В чем может быть причина, по которой окстор не запускает в админку?
