Question Install/Update Failure 4.0.10

Getting error message please help? Are we going to lose our content. The closest resolved issue i saw was to uninstall joomla and reinstall. We have no idea how to do this our site has many pages and members and scared something can go wrong?

We are a nonprofit with volunteers and the person that was helping is ill can someone please help us?

Thank you

Try first clean cache. Then go to administrator/index.php?option=com_kunena&view=install
Else you need to disable all none joomla/kunena plugins, then install, after install enable the plugins.

write down somewhere which plugin you have disabled.

Did all this still nothing.

try with an other browser

Nothing? Tried on chrome, firefox and Safari?

I had this problem last night as well and seemed to solve it by clearing the Admin cache as well.



I hadn't realized there was a separate admin cache until reading it in someone else's post.

I have done that also and still wont worrk?

I hit this problem a lot! Today I was updating a website that was using K 3.0.8 and I was installing K 4.0.10. Obviously I took a lot of precautions before starting the update (backup the site, copy the backup off-site). Anyway, I used my usual installation method—upload file—the Kunena installer halted and, the only way I could recover, was to use the browser back-button. :pinch: :dry:

Ah, but all was not lost! Even though the "Kunena installer" had failed, go to Components » Kunena Forum » Configuration and, sure enough, the rest of the installation went ahead. :woohoo:

I've never run into the problem of having to "clear the cache". I realise this is the answer/response given most often by the developers but, to be totally honest with everyone, I've never had to do it! (And, as for trying with a different kind of browser, that sounds a bit absurd to me.)

So, maybe I'm just one lucky person out of 30,000? Or maybe I have more patience than other people?

Looks like I am running into the same sort of problem. Updated to 4.0.10 and now my categories all say they are Orphaned in the administrator. I can see them in the live forum and click on them but get a notice of "Access Denied-You do not have permissions to access this page.".

If I click on the category in the administrator, I get this error: "Call to a member function get() on string".

If I try to unpublish the category, I get a really scary SQL error, the start of which says: Duplicate entry '3' for key 'PRIMARY' SQL=INSERT INTO `#__kunena_categories`. This is followed by a whole lot of database speak.

I am attaching my configuration report.


I have placed the forum offline for the moment.
I have cleared all of the caches and tried other browsers.

I am afraid if I uninstall Kunena that I will lose all my forum content. Is this correct?

Thanks for any assistance,

Mike

"Call to a member function get() on string". is a php7.0.6 bug.

So i suggest to go to php 5.6
