Upgrading to EB 5.14 blank page on non-live site :-o

Hi Support

I know that you guys are recommending upgrading to EB 5 on a test site.
Seeing as how I have a second version of my Site that I have been keeping for a Joomla update I thought I would try the upgrade on this test version.

http://upgrade.finalbug.net/administrator/index.php

Yes I ran into a problem and I suspect that it is related to this issue here that I see when I have error reporting switched on:

Strict Standards: Declaration of JCacheControllerPage::store() should be compatible with JCacheController::store($data, $id, $group = NULL) in /home/finalbug/public_html/upgrade/libraries/joomla/cache/controller/page.php on line 199

What I did:

got Site ground to do the following for me:

ask your web hosting provide to update the following to:
1) memory_limit to 256M
2) upload_max_filesize to 64M
3) post_max_size to 64M

Which they did.

Did main Akeeba back up of my back up site and tried installing the installer via the extensions manager.

Akeeba back up kicked in and then it looked as if the upgrade was happening.

Maybe I should have switched this off as I have had problems with it over and over again.

Then it looked as if Joomla was updating and I was brought back to the Joomla Extensions manager page.

There was neither a confirmation or denial that this worked.

When I went to the EB component in the back end it looked very much like the old component.

Now when I try to log back into the back end I get a blank page.

Good news is that I have error reporting switched on.

You probably know that I had some IP issues recently.

Can you PLEASEEEEEEE do the following.

Give me an IP if you can not get in?

Find out what the problem is on the upgrade site.
Upgrade and check that things work.
Check the live site (should be pretty much the same) make sure that this problem is not there.
And do the upgrade on the live site.

http://finalbug.net/administrator/

Passwords etc should be the same.

I know this is asking a lot but…
You guys know that I have been very patient and I would like to get this fixed sooner rather than later :-)
I am anxious to avoid more IP pain…

Siteground do daily back ups and you are welcome to hit that Back up now button in Akeeba Pro.

thanks in advance

Paul
