We're having the same issue. I have several accounts (20+) hosted at Rochen.com. Rochen Host just upgraded to PHP 5.3 on their hosted plan/servers, and all of my Joomla installations running 1.5.23 and the latest release of Ninja Explorer (1.0.6) are giving us the same errors when we open Ninja Explorer in the backend.
Deprecated: Function ereg() is deprecated in /home/lakescou/public_html/administrator/components/com_ninjaxplorer/include/fun_extra.php on line 513
Repeated/Multiple lines like the above appear all saying the same thing, over and over. If you scroll through these messages towards the bottom Ninja Explorer appears.
Is there a recommended fix for this? Could I do a regx search and replace/change "ereg to preg_match"?
Is it just the "fun_extra.php" file, or are there others?
Can we continue to safely use Ninja Explorer and just ignore these messages until this is resolved? Or is this something that is going to be resolved. I thought Richie was working on something that was going to replace Ninja Explorer but I don't see anything listed. Unless I'm blind. Which could very well be the case. Tends to happen when you get over 160yrs old. :P
Do you recommend using a different file explorer. I've used "eXtplorer" but prefer Ninja Explorer as this is what our low level admins are used to as well.
Any suggestions are appreciated. I'm willing to do any testing on live accounts if you have a patch you want to try. Let me know if you need any further info.
Look forward to anyones reply. :D
