Can't Update in Joomla 2.5.17

I have ZHGooglemap 5.4.1.1 and my Joomla 2.5.17 shows I can update to 5.4.2.0. However the update doesn't work. No error is given, but the component is not updated. Please fix.

Hi.

I've checked. All work.

I've added *.1 version. And install all by updater. Now there are current versions:
com - 5.4.2.1
mod - 3.0.9.1
plg - 4.0.8.1


In JED I'll publish later

Still doesn't work for me. The indicator spins for a while, then the page blinks and when you check, the component is not updated. I am now on Joomla 2.5.18.

I did it for J!2.5.17 and J!3.2.1
And all works. Can you give me admin access to your site.

Hi.

Thanks for access.
I REALLY don't know why it is not updated.
I logoff from your rockthem account
I change template to joomla's default

I have only one result - only manual update (upload). May be you have installed some "system" plugin, which not allowed to do all file. May be you should look at joomla's site logs (when you try to install update - some features (PHP, or some other) is disabled or son=me errors appeared

There are no errors in the error_log and the site I gave you access is not the only one where the update does not work. I am on php 5.4. This is an up-to-date server and up-to-date Joomla 2.5.18 site with all other extensions up to date. I will do manual upload update, but you need to figure out what is wrong.

Also, where can I download the latest version? The download version is old.
