Hello Olivier
Well everything was OK after all the upgrades when I checked, but we just went live with the site after which I discovered this page had stopped working again!
So I may need your help after all.
I now have a live URL at least. I've disabled the problem page but I've made a copy of it here:
aberdovey-holidays.com/properties-2
There seems to be a problem with the security certificate, don't know if that has anything to do with anything.
Let me know if you think you'd be able to take a look
Best wishes
Jennie

Hi Olivier
I've done these things but as soon as I enable the jquery easy plugin, the mobile menu stops working throughout the site, even though I've only applied the modules to the properties page. So as it's live I've had to disable the plugin or the site won't work on mobiles. I can see that on the home page it is loading this when the plugin is enabled:

<script src="/media/syw_jqueryeasyprofiles/js/jquerynoconflict.js" type="text/javascript"></script>Would it help if I set you up with a login so that when you are ready to have a look, you can enable the plugins?
The report gave the following info if that helps:
Using the parameters of theprofile jQuery is loaded by the template Bootstrap is loaded by the template re-ordered header libraries removed 1script(s) removed jQuery library skipped the removal of removed jQuery library added the jQuery library removed 1 Migrate script(s) added the script removed 4 empty script tag(s)

Many thanks
