Suddenly a problem with editor - Javascript / DOM (solved)

Bazou · Post by **Bazou** » Wed May 16, 2007 2:38 am

Hi all,

I'm running weathermap 0.91 and all was working perfectly until Yesterday.

Yesterday I logged off my workstation and go back at home. This morning I came at work and get the joined message when I tried to use the editor.

I made absolutely no changes to my computer, and I tried to access the editor with 4 others workstations and I get the same error as well.

when I try iy with the cli I got:

Code: Select all

# php editor.php

Note: I already get this duplicate error when it worked.

Any idea what could be the cause?

Thanks,

You remember when we agreed that if it worked then it was OK? Well it doesn't, so it isn't

It seems like PHP is trying to load the same extension twice.

Yeah i remember

But It worked with this. Anyway, I commented the gd extension in php.ini.
There is no more these warnings but I can't still access the editor

If you look at check.php in the web browser, does it show that your web PHP is loading any additional config files? (this would appear just under where it tells you what PHP version you have). If it does, make sure that none of those also have the extension=gd.so in it. You need it once, and only once.

I forget to mention that check.php return YES for all tests.

The additional files are:

Code: Select all

The php.ini file was /etc/php4/cli/php.ini
The following additional ini files were read: /etc/php4/cli/conf.d/gd.ini,
/etc/php4/cli/conf.d/mysql.ini,
/etc/php4/cli/conf.d/snmp.ini

The gd extension was in gd.ini.
So, now it's OK but it seems that it wasn't linked with the editor error.

It would do. The functions do exist. The problem is that the error messages will get in the way of outputting the actual image data.

Your web php is reading /etc/php4/cli files? That sounds strange, but OK.

What was the actual editor error then? Don't forget that if you are running 'php editor.php' from the command line, then that isn't the same PHP that would normally run the editor.

Check.php running in apache is also alright.

The error is, when i go to the editor's URL in my browser, I can't no more access to it as it said that I need to have javascript and DOM enabled.

The fact is that they are. I didn't change any settings on my workstation since yesterday and I 'm using javascript right now (for Gmail for example :p).

If you view source on the editor page, is there anything unusual (non-HTML-looking) at the top? The editor hasn't really changed in over a year... My guess would be that this is still related to the same problem. It sounds like maybe the same issue, but for the web php (which is why I said check for duplicates in the web check.php list of ini files).

Ok, I just understanded what you mean. Apache read gd.ini too, which was created and linked during the installation of the debian gd package. So on debian there is no need to edit php.ini for both cli and apache.

Now that's OK. But it doesn't solved the problem.

On the page's source, I got LOTS of these errors lines:

Code: Select all

<b>Warning</b>:  feof(): supplied argument is not a valid stream resource in <b>/usr/share/cacti/site/plugins/weathermap/editor.inc.php</b> on line <b>52</b><br />
<br />
<b>Warning</b>:  fgets(): supplied argument is not a valid stream resource in <b>/usr/share/cacti/site/plugins/weathermap/editor.inc.php</b> on line <b>54</b><br />
<br />

These 2 lines are repeated infinitly.

Hope it helps.

Sorry - that was a little complex.

OK - that is where the editor is reading the config files in the configs/ directory to see if they have titles. Are any files in there unreadable by the webserver?

Yes! you got it

There was a "simple.conf.save" created by root yesterday. I don't know how it appears here but the problem is now solved

thank you Howie!

I'll try and fix this in the next release. It shouldn't really bring the whole thing crashing down like that.
