Zotonic Master - blank admin page

[Simon Smithies]

Hi all,

On a clean clone of zotonic master, the Admin page comes up empty. Am keen to play with the new bootstrap stuff ... is it straight forward to get master working? Or should I be patient and wait for a release?

- Simon

[Marc Worrell]

Hi Simon,

I didn't try a clean install yet :)

We are working with the master, in fact we are almost releasing a site with it.
Maybe you can enable the mod_base_site on the command line?

z_module_manager:activate(mod_base_site, z:c(yoursitename)).

- Marc

[Simon Smithies]

Hi Marc,

Thanks for the reply and sorry it's taken me so long to get to it.

That command got my site running, but I'm still not seeing the top level admin page (the one that where you start, stop, flush etc your various sites), and I still get nothing when I append /admin to a specific site - where expect the login form.

Well done BTW on your 0.9 site - that proves it can be done!

- Simon

[Amiramix]

Simon, do you still have those issues? I had similar problems that I managed to sort out and maybe able to help if the issue still persists.

[Alexey Marunin]

Hi,  Amiramix!

I had similar problems that I managed to sort out and maybe able to help if the issue still persists.

I have similar problems :)

No sites, just zotonic_status. I entered admin password, but see blank page.

PS. I noticed that admin password send by GET. Is this safe?

[Arjan Scherpenisse]

I dont really think the admin password is sent using GET. Rather, it
uses POST to the /postback URL.

How did you come to this conclusion?

[Alexey Marunin]

Hi Arjan

 

I dont really think the admin password is sent using GET. Rather, it
uses POST to the /postback URL.

How did you come to this conclusion?

After entering the password, I saw URL like "username=admin&password=VXb4ym9k" in the address bar 

PS. Google Chrome 21.0.1180.89

[Amiramix]

OK, lest establish first when do you see the blank page. Is it when you try to open zotonic_status or your site? Above you mentioned that you can't login because you see a blank page. Here you say that you could enter admin password. Can you please write down which pages you visit and where is the problem? BTW my problem was that the logon page to the admin section wasn't being shown because the default base.tpl wasn't in my site. I fixed that and it has been integrated to Zotonic. Have you tried to sync to latest Zotonic sources? What happens when you try to add a new site?

OK, maybe I do not fully understand what is being said (thanx Google translate)

No additional sites, just zotonic_status

See blank page (is it admin page?), URL is http://helentana-dev.ru:8000/postback?username=admin&password=tvWwdrk7

Hi Alexey,

When you see "/postback" in your url then something went wrong with the post back to the server.

Most often it is a javascript error.

Do you have javascript enabled?

Do you see any javascript errors in the console?

- Marc

[Marc Worrell]

I just checked the URL in your message.

The page doesn't load any css or js files.

There are 500 errors from the server.

What version of Erlang are you running?

I think filename:extension/1 accepting binaries was added in kernel 2.14.2 (R14B02)

We should add a warning that we need R14B03 to run.

(stay clear from R14B02m, see https://github.com/zotonic/zotonic/issues/245)

Especially as we are moving forward with new NIFs, binary module use and unicode.

There is quite a bit changed since then :-)

The pictures is probably an ImageMagick problem.

Make sure that you have a relatively new version (say max 2 years old).

Some Linux installs come with ancient versions from around the previous ice age.

Amen. You may be running a version that works fine, apart from not supporting the --layers flatten option. In which case you might want to comment that out.

Zotonic seems to start ok now, but there are still problems with the rpc. Good to see that 'zotonic status' also errors, so it's not related to the erl_call command per se

Do you do the addsite command as the same user that zotonic is running as?

I'm using two putty consoles: one for ./start.sh and second for addsite. But login the same user

Alexey, Do you still see the problem with the blank page that you mentioned originally in this thread? What happens when you open the zotonic_status page and logon to it? Or is the rpc call (addsite) problem the only problem that you have with Zotonic at this moment?

Both :) 

Cannot add new site - zotonic say that he doesn`t run

And see blank page when enter password on zotonic_status page

Do you think these problems have the same reasons?

Once you've upgraded Erlang, what now do you see in logs and in the console after you enter password on zotonic_status page?

O_o

I uninstalled ImageMagick. 

Then I tried to download ImageMagick 6.7.9-8 sources and build them. But failed:

gcc: Internal error: Killed (program cc1)

:(

Then I installed default ImageMagick and updated zotonic from google repository

Run ./start.sh

Open http://helentana-dev.ru, enter password - and WIN! It's work!

But I do not like that magic... The reason of problem is still unknown for me

Whatever

Thank you all for help! And for your patience :)

PS May be show Zotonic current version near copyrights?

The current version of Zotonic is shown in your own site, not in the admin section. But in any case, if you sync from git then it's always 0.9-dev. The version would really need to be the git commit, otherwise it would need to be increased almost every day.

Good that zotonic_status now works, now about add-site? Did you try the commands from the other thread?

Thanks :)

I have two version of zotonic: 0.8.1 (I called it "stable") and 0.9.0 ("dev"). In my experience, it's good practice - production version of site works on stable engine, and all new features I test on dev-engine :)
