Frontend or backend? Which WYSIWG editor are you using? Is it up to date?

I'm having the same problem on a brand new, clean installation running under WAMP on Windows 10. I can create single and repeating events but the description does not get saved. I have also tried toggling multi-category events but this makes no difference.

PHP Version : 7.0.0

MySQL Version : 5.7.9

Server Information : Windows NT DEREKS-LAPTOP 10.0 build 14372 (Windows 10) AMD64

Fix jQuery? : Yes

Load JEvents Bootstrap CSS? : Yes

Max Input Vars ? : 2500

Club code set? : No  

User Agent : Mozilla/5.0 (Windows NT 10.0; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0  

Joomla : 3.6.0

component_com_jevents : 3.4.13

module_mod_jevents_cal : 3.4.13

module_mod_jevents_custom : 3.4.13

module_mod_jevents_filter : 3.4.13

module_mod_jevents_latest : 3.4.13

module_mod_jevents_legend : 3.4.13

module_mod_jevents_switchview : 3.4.13

plugin_content_jevents : 3.4.13

plugin_finder_jevents : 3.4.13 (not enabled)

plugin_search_eventsearch : 3.4.13

plugin_system_gwejson : 3.4.13

I have not tried updating the event description via phpMyAdmin as I haven't found the right field yet (hint, please <!-- s:!: --><img src="{SMILIES_PATH}/icon_exclaim.gif" alt=":!:" title="Exclamation" /><!-- s:!: --> ) but I'm anticipating that it is not getting saved.

I'll be watching this thread with interest as it'll probably be the same problem/resolution. If you need any more information let me know.

Added:

TinyMCE - changes to the description field do not get saved.
CodeMirror and 'none' - changes to the description field do get saved.

All editing in my system is being done in the back end at present.

thanks - that was very helpful. I have recreate the issue and am now working on a fix.

Thanks. As a temporary work-around I've installed the Switch Editor plugin from Anything Digital. I can see it being a useful tool for other content pages anyway.

I found a workaround to this problem in TinyMCE.

Change line 533 of administrator/components/com_jevents/views/icalevent/tmpl/edit.php from

<?php echo echo $this->form->getInput("jevcontent");?>

to

					<?php  

                                        // There is a TinyMCE issue in Joomla 3.6 where it loads the javascript twice if we do this

                                        //echo $this->form->getInput("jevcontent");

                                        // so instead we use the value we already have in the replacetags

                                        $index = array_search("{{DESCRIPTION}}", $this->searchtags);

                                        if ($index !== false){

                                            echo $this->replacetags[$index];

                                        }                                        

                                        ?>

Hello Geraint
I got the same issue!
Thank you very much for taking care of this problem!
Best regards

JEvents 3.4.14 includes this fix and is available for download now.

Just discovered this problem on my site yesterday. Thank you for having a fix up so quickly!

Glad to hear you got it resolved :-)
