Then you should write for example:
1. Unzip the package to your hd
2. Copy whole /upgrade/ inside unzipped package to your server place
3. Delete htdocs/mainfile.php, htdocs/install/, htdocs/cache/, htdocs/extras/, htdocs/template_c/, htdocs/themes/ and htdocs/uploads/ from the unzipped package on your hd.
4. Copy the files inside /htdocs/ to your server place, overwrite all.
5. Run /upgrade/ from your XOOPS site.
6. Follow upgrade instructions on your XOOPS site
7. Delete upgrade folder from your server place

That makes more sense between server place and your hd. :)
With very short instruction, i'm not sure if it's for server files or for zipped package...

When i try upgrade from 2.0.16 to latest 2.0.17.1, i follow the upgrade instructions:
1. Move the "upgrade" folder inside the "htdocs" folder (it's been kept out as it's not needed for full installs)
> Done
2. Delete htdocs/mainfile.php, htdocs/install/, htdocs/cache/, htdocs/template_c/, htdocs/themes/ and htdocs/uploads/
> Most strage is to delete Themes and Uploads folder. The some files from another modules are stored in Uploads folder. Why should i delete it? Very bad advice. I have own theme, thus i cannot delete whole directory. Deleting mainfile.php is also idiotic, because you lost DB settings, which you need for upgrade process. Why!!!
3. Upload the content of the htdocs folder over your existing files
> Done.
4. Access < your.site.url >/upgrade/ with a browser, and follow the instructions
> Bang! It doesn't works. It suddenly jump to < your.site.url >/upgrade/install/index.php which is NOT here! The script is useless! Then after some tries i discovered the file mainfile.php MUST not deleted. Or i must put it back after step 3. Without mainfile.php, upgrade process is not possible. But you can fix the mainfile.php with < your.site.url >, which jumps automatically to install page. Fill the DB settings and it build new mainfile.php. Now you can skip another steps and go to /upgrade/. The upgrade process is now possible.
5. Follow the instructions to update your database
> No problem after fixing mainfile.php
6. Delete the upgrade folder
> yes yes....

You can see, i follow exactly your XOOPS upgrade instructions, but it has serious faults. Deleting mainfile.php cause errors by upgrade process, it jumps to install mode, and it gives white page! It's really stupid joke. And why delete whole Uploads folder? No thank you! If it has megabyes data, i don't want delete it. Idiotic advice.

Please give me explainations why i must delete mainfile.php and Uploads folder? Well?

Confirmed the error is caused by little error inside Wowroster script. When Wowroster is disabled, the userinfo.php page works.

Maybe for some users who userinfo.php page does'nt work:
- debug first which error it gives (best is debug in popup option, not Smarty version) so you can see parse errors.
- unload some modules from XOOPS until the page works normal. Then there is some error in the module part. You can also disable it, that works too.

I have 2 installs on local pc (with local apache running) and one at colo server.
Both are working perfectly, only userinfo.php don't show anything.
Local apache has Windows. All directories are writable.
Colo has already set some directories writable, but still same empty page.

I can look at older version builds if the problem is still there or not. I shall try also clean and fresh install again and check if the problem is same.

I give you the results about userinfo.php with fresh install and older builds.

EDIT: I have turn debug mode on.

There is error given when loading userinfo.php:
Quote:

I better talk to wowroster crew about it.

Soon i shall test at home the installs.

When i have just installed XOOPS 2.0.16, the installation is smoothly and i have made new site.
All modules are succesfully added. Great.

But now there is VERY small trouble. Only userinfo.php doesn't give the page. It's empty. When i checks where is the trouble, i discover the foreach part at the end of userinfo.php doesn't build the page and ignore whole part.

When i do the count($mids), it counts 7 records. The data collect works before, but it doesn't want generate the page.

The page edituser.php works good. Why not userinfo.php?
How can i fix the problem, if XOOPS works for 99% and not this?

i'm now debugging the userinfo.php what the real problem is.

Edit: receiving modules works, but it doesn't make the pages. Perhaps there is invisible error.
