Upgrading Drupal

I tried to update from 4.7.4 to the latest 4.7.7, but got the error message

Fatal error: Cannot redeclare system_update_110() (previously declared in /mnt/web1/20/10/5126210/htdocs/soccer-wikki.net/database/updates.inc:5) in /mnt/web1/20/10/5126210/htdocs/soccer-wikki.net/modules/system.install on line 508

Luckily, this is just the test side ...

Please help ...

I upgrade 4 sites to 5.2 from 5.1.

The data and time in nodes only can see in english format. The site is in catalan and spanish ..

From the apache log:
[client 66.13.27.1] PHP Fatal error: Call to undefined function: taxonomy_get_tree() in /var/www/html/includes/common.inc(1201) : eval()'d code on line 8, referer: http://mail.thecitizen.com:10237/admin
[client 66.13.27.1] PHP Fatal error: Call to undefined function: banner_display() in /var/www/html/includes/common.inc(1201) : eval()'d code on line 6

The site is pretty much dead in the water.

Hi my (800 plus node) site broke updating from 5.1 to 5.2. Did everything (11 steps) from the manual and things looked fine in the beginning. However, all my personally added content types proved to be gone. This was probably my own fault: I accidentally copied an older Views into the modules directory. I use Views, CCK, Date, Scheduler and MyCaptcha.

I upgraded to 5.2 a couple of days ago. I wanted to change the theme to day and I can't change it. It gives no errors and when I says Saved. But it doesn't save.

There are a few posts where I've noticed that people having problems with an upgrade to 5.2 seem to be having that problem when dealing with views, rather than standard vanilla nodes. More specifically, it seems to have these characteristics:

- a view
- a block view
- a block view set to "full node" rather than "teaser list" or any of other options
