Backoffice 500 Internal server error

[aliejus]

Hello,

   Installed fresh presta 1.6.09. and when I'm browsing in backoffice very often appears white page with:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

 

I had presta 1.5xx version and there wasn't any such errors. I also find an article how to find error but only in presta 1.4 and 1.5. but these ways not working on 1.6.

I'l appreciate any help.

THanks

internal server error 500 = errors

please turn on error reporting and then instead of internal server error you will see detailed information about problem (what and where doesnt work)

ohh noo, my stores turned into a error 500 page. I had no Dreamweaver files or editing programs open, so its not as though i altered any files... i was just simply uploading some stock photos, then was met with the error message. I cleared the cache, and tried again, still an error message.

 

I followed instructions to turn on error reporting.....

1. Open config/defines.inc.php
2. On or around line 28 you will find this line
   define('_PS_MODE_DEV_', false);
3. Change that line to read
   define('_PS_MODE_DEV_', true);

i cleared the cache then refreshed the page, and it reads the same error message...offering little details on whats happened.

 

i checked file permissions...all 755

 

i cant access the back office or the front office.

For anyone else with this issue

prestashop 1.6,  uploading images and met with error 500 page. turned on errors, and didnt understand what the error message read.

 

"The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@..... and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request."

 

(i found articles to assist, but most of the steps to fix the situation required access to the back office. I had no access to front or back office)

 

so in dreamweaver or other editing program, i opened file .htaccess (theres a few of these i noticed so i opened the first one thats visible located in the WWW file directory.           /www/.htaccess

 

line 7 where it says “SetEnv HTTP_MOD_REWRITE On” i put a # before it (#“SetEnv HTTP_MOD_REWRITE On”)

saved the file to the server and i was finally able to gain access to the back office.

 

Im guessing it was the URL rewriting which caused the issue, and how to correct it is something i have to look into further, but this atleast gave me access to the backoffice again.

 

for all those prestashop geniuses out there, your proberbly thinking, "well duh" but for those not familiar with programing etc like myself i hope this helps
