White screen problem, $chat->nick

program...@gmail.com · 2013-11-21 21:42:25

Hello

I have a dedicated server and installed LiveHelperChat on a subdomain of my website

http://live.mywebsite.com

I have white screen problem continuesely , however sometimes it works without problem.

usually when i receive a chat request, this will happen.
i can not see notification but i can see pending chats if i click on "Pending chats" link, but there is no icon there to start chat.

i did all debugging things which i found in documentation about white screen.

i dont see any error message anywhere, and no error in my Apache logs.

I tracked don issue until i saw something is wrong with "/index.php/site_admin/chat/syncadmininterface/"

it should return json normally, but it doesnt when this happen.

i found issue is happening in "pendingchats.tpl.php"

when i monitor "/index.php/site_admin/chat/syncadmininterface" calls, i get this response from server :

<ul class="no-bullet small-list">
<li class="chat-row-21">
<img src="/design/defaulttheme/images/flags/gb.png" alt="United Kingdom" title="United Kingdom" />
&nbsp; <img class="right-action-hide action-image" align="absmiddle" data-title="

And it stops at datatitle="

I took a look at that file and saw its happening in "syncadmininterface.php" , here :

$tpl->fetch('lhchat/lists/pendingchats.tpl.php')

in tpl file, it stops at this call : data-title="<?php echo erLhcoreClassDesign::shrt($chat->nick,10,'...',30,ENT_QUOTES);?>"

i didn't go further though.

How can i see whats happening in there? do you log $tpl->fetch errors somewhere?

any help would be appreciated.
Thanks

Do you have installed mb_string extension? In any case you shoud see atleast something in your apache error log. Without error itself i cannot help and white screej does not helps smile

Hi
Thanks for all your help.

Seems mb_string was cause of problem.

maybe you can check that at installation time? i think other users may face that problem.
i saw that someone in forum had exactly same problem as me and fixed it by changing his hosting.

Thank you by the way smile
