It was an issue with Mootools library not FF18

Mootools function getElement( "input.kfile-input" ) was finding

<input class="kfile-input-textbox"> instead of <input class="kfile-input hidden">

fixed by using getElement( "input.kfile-input.hidden " ) instead

Thanks for reporting.

Many thanks for your reply.

having the same problem using joomla 1.5 with kunena however we have a test site using joomla 2.5 and that works ok. Still have this issue

Try changing the following 2 files:

in /components/com_kunena/template/default/js/editor.js

var input = __file.getElement('input.kfile-input')

to

var input = __file.getElement('input.kfile-input.hidden')

in /components/com_kunena/template/default/js/editor-min.js

var a=c.getElement("input.kfile-input").set

to

var a=c.getElement("input.kfile-input.hidden").set

Many thanks fro the response.

SOLVED

Thanks WooDzu alas it did not work on our site.

What version is your site running?

Our is MooTools 1.2.5 (from MooTools Upgrade plugin), a minified and compressed version.

Same version

I could take a quick look if you share your site's URL

www.goldwingforum.co

you will need a user name

user: test password: forum

Thanks. Well, I can see the same issue on your site.

Replaced your editor-min.js with the one from www.lwks.com and it works fine for me on FF18. The only issue that I can think of is that when you edited the file it added some unnecessary backslashes to it, which now causes syntax errors see Firebug/Chrome inspector.

To fix it you can try replacing you js with the one from lwks.com or even better reverse your changes and use a different editor to apply the above solution.

ok will have a go with a different editor, many thanks

replaced both file with backups and modified using another editor, no more lines but still not working.

When i checked with fire bug got this line

<input type="file" name="kattachment" class="kfile-input hidden" id="kupload">

the . between input and hidden is missing although it is in both files, i am not sure where this code is but putting a . in with firebug shows up the browse button.

Any help would be appreciated again

I see the forum attachments are working back again

Still not getting them here, all we are getting is add file but when you press it it invites you to add an image you select one press open and nothing appears, before you had an extra set of commands like add and insert but nothing now. Its the code i see using firebug, the . appears to be missing but this gives a browse button which we never had before

Perhaps the editor-min.js file got cashed by your browser. Try clearing the cache or use Firebug to switch it off temporarily

Double checked now, and it looks fine from here

you were correct again, been clearing it all day, not that time, yes it has come back to life. found out some interesting stuff today, do not use ACE FTP to edit files a sit seems to add lots of /////////////////////

and keep clearing cache. Many thanks for your patience and help WooDzu

Glad to hear it's fixed.

the ADD FILE button works with Firefox v17esr or older but NOT with v18.0 or newer...
