Problem; "Notice: Undefined index:"

Hi,
I've installed a few plugins lately. I tried disabling the plugins.
but I keep seeing this error;

Notice: Undefined index: route in /home/username/storage/modification/admin/controller/common/header.php on line 26

The part where the error occurs is the admin login screen.

obviously you did not disable all the modifications or did not refresh modifications having done so.
At the very least if you disabled all the plugins the file would no longer be in the modifications folder.



The error is on line 26 of the file storage/modification/admin/controller/common/header.php
Since it is modified we can have absolutely no idea what that may be.
1. Start by disabling modifications that effect the header
2. Look at the file itself and see what the line is
3. The error is a notice - that means "I am just making you aware that " - it is not a good thing, but it is not critical either - if you were a good developer you would fix it , but it is only a NOTICE.

BEWARE : error logging should NEVER be enabled on a live site.

Once you have followed OSWorX link and provided more information maybe someone can help you.

In your case, there's no point in editing the files. The problem will return with every refresh of the modification. It's best to edit the modification in the database. Where the script calls for "route," add a condition, for example, if(isset($route)). Find out which modification is causing the error, edit its entry (e.g., in phpMyAdmin), find the problematic variable, and add the condition.

I've installed a few plugins lately.

Which ones? Have you emailed the extension developers?
