Hello,
I have installed mobilejoomla in my site where I'm using tienda shopping cart.
When I try to pay and order with paypal it break payment validation process and in FF Error Java console I find:

"Error: illegal characterSource File: www.xxxxx.com/plugins/system/mtupgrade/mootools.jsLine: 1, Column: 112Source Code: 10px;\"><b>Checkout Amount:<\/b> \u20ac297.50<\/div>\n <img alt=\"\" border=\"0\" src="/\"https:\/\/www.paypal.com\/en_US\/i\/scr\/pixel.gif\"\"1\"\"1\"" \ />\n  <div style=\"clear: both;\"><\/div>\n"

This is because seems that with joomlamobile installed returned html content is not correct infact html appears like below ( In RED color where FF show illegal character error)
 <img alt=\"\" border=\"0\" src="/\"https:\/\/www.paypal.com\/en_US\/i\/scr\/pixel.gif\"\"1\"\"1\"" \ />
insted of
<src=\"https:\/\/www.paypal.com\/en_US\/i\/scr\/pixel.gif\" width=\"1\" height=\"1\" \/>
So HTML is breaked and return JS error.

I'm using
Joomla 1.5.25
MobileJoomla 1.0RC6
Tested on Iphone4 IOS5 and FF with IphoneSwitchUserAgent to Iphone 3.0

MJoomla is configured to not remove unsupported tags but problem still also with option enabled.
I have search on forum for same problem without results.

If you need to check error on my site I can send data as private message/email with FTP account.

Thanks a lot for any feedback

I confirm bug. Is necessary to disable image resize to make it works.

Could you send URL of your site?

Hi,
I have solved problem by setting iPhone configuration tab "Image adaptation method" in "Don't rescale".
Infact joomlamobile parsing the return back html row code to search image tag to rescale and break HTML code.
Joomla mobile break below tag (as you can see is not a properly HTML code)
<img alt=\"\" border=\"0\" src="/\"https:\/\/www.paypal.com\/en_US\/i\/scr\/pixel.gif\"\"1\"\"1\"" \ />
instead of
<img alt=\"\" border=\"0\" src=\"https:\/\/www.paypal.com\/en_US\/i\/scr\/pixel.gif\" width=\"1\" height=\"1\" \/>
I don't need to rescale any image because I have resized image properly for mobile template.
Now all works good.

When user click on paypal buttton on tienda it return a row code like below.
MobileJoomla seach for image tag to rescale it and break code.

Does the issue arise in 1.0 Stable?

Yes. I have update today to latest version but problem still if I enable image resize. All works good with "Don't rescale" setting.
