Sounds to me like you have some scripting errors.
Check your Wp theme for the way it is loading jQuery.

The second question is resolved I think 🙂 Could you tell me where I can check how my wp theme is loading jQuerys? But I think it’s not related to my theme, because one member is able to quote, but he is the only one

I can tell you if you give me a link to your forum page.

www.wparea.de/forum

for example look at the last post at: http://wparea.de/forum/windows-phone-7-apps-forum/facebook-app-wurde-geupdatet/

I noticed that he was quoting over a mobile phone with IE mobile. I tried it also over my WP7 smartphone and it worked (although the quote is shown on mobilephone with mobile template incorrect but on PC correct)

Edit: We are also not able to insert youtube videos in posts. The plugin is enabled but it does not w ork :-/

I can’t try it as you need an account to post.

I would not be surprised in the least if the quote does not work from some mobile devices. Many are behind on decent javascript support.

You do not need a plugin to post youtube videos. Just paste the youtube url straight into the post. If you have oEmbed turned on in WP media settings it will work.

I think you misunderstood me 🙂 On mobile phone it worked (but we tried it just on a wp7 smartphone). On the PC it does not work. If you want, you can create an account in order to test it. This would help maybe :-/

The video insert problem is solved.. thank you! 🙂

youtube videos are inserted via oembed… just paste in the url… if you try to embed the object yourself using an iframe, it wont work since us allowing iframes would be a big security risk…

Thanks I solved the embeding Problem but quoting still doesnt work. I asked the template designer if he can check this but no answer since now. If you want, you can look over this by creating a test account on my forum

Sorry – I thought you implied that this was only a problem on mobile devices.

As a matter of policy we do not register on users sites. If you want us to take a look please create a user account and then send a PM to both my self and to Mr Papa with the credentials, a link to your site, a link to this thread and a brief reminder of the problem and one of us will come along and take a look.

you have a plugin that appears to be way out of date and causing js/jquery issues on your site…

the SI Captcha anti spam plugin is trying to load an ancient version of jquery with:

<script type=’text/javascript’ src=’wp-includes/js/jquery/jquery.js?ver=1.2.3′></script>

and of course it cannot be found…  wp is using version 1.7.1 of jquery and several versions ago moved the location of its jquery in wp-includes…

dont know if that is causing your issue but is causing problems…

Hmm.. okay and do you know how to find that plugin, which is using out of date and causing js/jquery issues?

Update: I found that plugin, I think its pie register (register plus). I disabled it and checked on google webmaster tools if it is still loaded and it’s not. After this I tried to quote and it still does not work…

its still trying to load for me…

<script type=’text/javascript’ src=’https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js’></script>
<script type=’text/javascript’ src=’http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js’></script>

the js at least partially works but something is still wrong…  not only is the text not copying, the page is not scrolling to the editor when opened…

you really should resolve the jquery loading stuff – loading some minified version from googleapis may not equal loading the wp version…

also, if you could add:

define(‘SP_SCRIPTS_DEBUG’, true);

to your wp config file, I can try to debug the js and see where its heading south…

After i wrote my last post here I activated the pie register plugin, because nothing changed in the forum. In this moment I deactivated ajax login and pie register and quoting still does not work. 

I added define(‘SP_SCRIPTS_DEBUG’, true); to my wp config.php

Hope you can help me :/ 

Thanks

I am not able to detect the exact problem from my side… so lets do a bit more debugging…

can you temp switch to the default wp theme and see if things work better?  might help narrow it down…

if that does nothing, then disable your other plugins and see if it works… if so, then reenable one by one until it breaks… again, just trying to narrow it down…
