Error editing articles in "front end"

Hello,
I get an error editing articles from the front end. The link "entry", "image" and "page break" under the text area give the error "500 - JHTML :: Bootstrap not supported. File not found.

Unfortunately does not allow changes to users that do not connect to the back end.

I'm using the hotstart version, with Joomla 2.5.17

Thanks

Max

Joomla 2.5 does not have bootstrap did you maybe edited index.php of template here:


if (preg_match("/2.5/i", JVERSION)) {
JHtml::_('behavior.framework', true);
} else {
JHtml::_('bootstrap.framework');
}

No, I have not changed .. the instructions are there.
I am attaching for inspection.
Thank you!

Did you maybe installed something intended for j3 on j2.5

Hi Ivan,
as I said, no installation of modules or components. I understand the fear of my mistakes, but if you download the file "hot_app25_hotstart.zip" and create a site can quickly verify the error.

If you want, I've created one. I added only "login" to access from the front end. I am sending username and pwd separately.

Hello

You can try to use different editor, JCE for example
