Just tested other areas (articles, categories, and etc.) where the search feature exists, and the same issue. Can't clear it.

Please test on staging as I can't reproduce here.
https://github.com/joomla/joomla-cms/archive/staging.zip

hmm, there is another issue for the same topic where the version of PHP is pointed as responsible.
#8421

See my response JM on #8421 I confirm the issue

So what's the verdict here? Do I need to tell my host to update PHP, if yes to what PHP version? Or will you guys figure out a fix for us?

I just updated to Joomla 3.4.6 and the issue is still there, unfortunately.

P.S. Since the last time I reported this issue, it seems that my host has updated PHP to 5.6.16 -- and the problem still exists on my side.

Just letting you know that I've updated to Joomla! 3.4.7 and this problem/bug still exists.

Added two known workarounds.

Could not reproduce the issue
PHP 5.6.11
Joomla 3.4.5 ~ 3.4.8

I've reported this on more then one occasion and am constantly told it
doesn't exist. I can verify that in fact DOES exist.

@N6REJ Please perform one more test as I mentioned in #8421 (comment).
We are still working on to find and fix the issue, don't worry.

Set to "closed" on behalf of @infograf768 by The JTracker Application at issues.joomla.org/joomla-cms/8641

Closed as not Joomla Core.

Not sure if my host has Suhosin installed or not. I just sent them an email to find out. I hope this fixes this issue on my side also.

I echo what @N6REJ stated above about trying to fix this issue on Joomla's end. Other software like phpBB, Vbulletin, Wordpress and etc. Don't have this issue.

@MixingOnBeat please ask your host to set suhosin.request.disallow_nul=Off instead of "on" which is the default and let me know if this fixes it.

Troy that is no solution. It disables Suhosin (which is "hardening" of
PHP and very much needed) and is a bad advise imho

It was as a test to be sure I was on the right track... I was reading in
suhosin git and that apparently is the issue which is why they updated
suhosin, now, IF that does solve it, which I bet it will, then we can
change joomla so its outputting a empty string instead of a null to
$post can't we? if_empty() treats null just the same as "" or '' so ......

@N6REJ, my host won't do it. Since I am on a host/shared server, what affects my site affects others.

Hopefully you can figure this out. I think Joomla needs to find a common ground here.

@MixingOnBeat makes sense... perhaps @izharaazmi can check if what my suspicion is is true and then fix it

I'm still having this issue with Joomla 3.5

Site Information:
OS Linux n
PHP 5.6.17
MySQL 5.6.29
Caching Enabled
GZip Enabled
Articles 204

Since this is essentially not caused by Joomla, it will be observable with
any of the PHP application out there.

However @MixingOnBeat, if you want me to fix it for you I can develop a Joomla
plugin for you.

I still recommend to fix your suhosin installation or move to another host.

@izharaazmi
Izhar,
Just to confirm that installing the later version of Suhosin all is still working with Joomla 3.5.0 & J3.5.1 RC1. As discussed and resolved previously this is indeed cPanel's Suhosin version causing the problems.

I think it would be a good idea if you could find the time to address this with a plugin (found a descent amount of posts on the Joomla forums on this) and since it seems that this will not find a "home" at/in Joomla I am most willing to list it (as your product) on the JED with a download-link from gws-desk.com (free of course) as token of appreciation. You have my email and I have yours so we can detail this off-Github

@gwsdesk I emailed you regarding the test env for said plugin. Probably you didn't receive that. Well I do not have the setup to test it therefore I am putting it on github today, untested.
You can always tell me when it doesn't work.

@izharaazmi I would be very glad to test the plugin also. Tried to find it on your Github account but only readme is found.

@MixingOnBeat @gwsdesk @UWiX-nl I have uploaded it at https://github.com/izharaazmi/joomla-suhosinfix

@izharaazmi: thanx! That does the trick for now. Already in discussion with my hosting provider about this.

izharaazmi I did miss your email I am sorry and found it. I have tested this on a box and can confirm this works like a charm. Nice one!

I created a plugin to workaround this issue. You can download it here https://github.com/izharaazmi/joomla-suhosinfix/releases.

Endorse me on LinkedIn, if you feel like.

@izharaazmi just loaded your plugin on Joomla 3.5.1 and it's working good.

I tested the search function first to see if in case 3.5.1 update would fix it, but no. So I then loaded your plugin and enabled it. Now I can clear my searches in the admin panel.

Thanks! :)

Glad that I could help. I have posted this at few places where I could find this topic. If any of you find this anywhere else please share this plugin with them too.

Nice one - the latest update of Joomla (3.5.1) didn't fix this indeed. But the plugin works perfectly!
Also reported this to my hosting provider and with the information on this page (thank you izharaazmi) the have scheduled an update of Suhosin :-) Way the go Hosty (hostingtime.eu)!

Thank you for the great plugin izharaazmi!
