Hi, i keep getting this warning when i try go to Categories / Products.

Warning: mb_strstr() [function.mb-strstr]: Empty haystack in /home/mysite/public_html/admin/includes/init_includes/init_file_db_names.php on line 20

Is this a stock install or what mods have you installed?

[JayNT]

the site has been up and running fo ra while ..BUT from what i can remember
it has the how did you hear about us 1.3.7 mod and i have recently tried using the define pages generator . And also i have Nochex setup as a payment option .

Try using the developers tool kit and search for mb_strstr() to find the file this is in...

I checked a stock install and got no hits and why I asked what mods you had

[JayNT]

tried dev toolkit .......
it found nothing

[kobra]

did you enter in last/bottom left box and select all files catalog & admin?

Determine what mod added mb_strstr if this was a mod and back it out

[CarolineBogart]

I know this is old but I am seeing it today, and have 2 cents to add.

mb_strstr isn't called by anyone, it's an internal function to strstr.

In this admin/includes/init_includes/init_file_db_names.php file line 20, the $_SERVER['HTTPS'] and $_SERVER['HTTP_X_FORWARDED_BY'] are empty, hence the haystack is empty to the internal strstr function mb_strstr.

$request_type = (strtolower($_SERVER['HTTPS']) == 'on' || $_SERVER['HTTPS'] == '1' || strstr(strtoupper($_SERVER['HTTP_X_FORWARDED_BY']),'SSL') || strstr(strtoupper($_SERVER['HTTP_X_FORWARDED_HOST']),'SSL')) ? 'SSL' : 'NONSSL';



This is a mis-configuration on the hosting side that is not passing these two variables.
