i cant active drutex module

I can not guess any reason for an http 500 error.
Can you help me with some information to reproduce the issue?

The same error goes to
me

when i ticked "enable" and saved it , then it turned out being not ticked and enabled, i tried many times, same same, no error message, just keep being unenabled,other modules are normal.

in error log : PHP Fatal error: Call to undefined function dpm() in ... public_html/modules/drutex/drutex.module on line 862 ...

maybe the latest dev version is ok

@ assenal: Ok, The last dev version is OK, Please use it. I will release a new version of DruTeX as soon as possible.

I had the same problem with activating the module. I upgraded to dev, which allowed me to enable. However, when on the content types configuration page, I get a bunch of warnings now:

I had run update.php, but there were no available updates to the database. I am running Drupal on a Postgres backend, with Apache.

Cheers, Lars.

Hi,

The same issue for me.
I'm running with MySQL et Drupal 7.12

Merci

I can do TeX but I've got this errors :

Thanks

I am having same problem activating Drutex on module page. Here are my symptoms:

When I navigate to modules page and try to activate Drutex, browser navigates to

http://example.com/admin/modules/list/confirm
which displays the modules page (with Drutex still disabled)

When I try to activate it for the second time, it takes me to the same URL, but it is a blank screen instead of the modules screen.

I have texlive installed as well as dvipng using apt-get but I did not change their install path and I've read that they need to be installed in the "root" directory in order for Drutex to work. Is this true? And by "root" do they mean my server root or my web root directory?

Same problem ... using drupal v7.12
- running 7.x-1.0-alpha1: undefined function dpm() on enabling module and trying to save configuration
- running 7.x-1.x-dev: Notice: Undefined index: remote in _filter_drutex_settings() .... on setting up text format configuration

Bump. After more than half a year, the "recommended" version still contains a critical bug (failing to enable module), and the dev version spits out large amounts of errors without any comment from the mod author.

This makes the module more or less unusable. Is the mod author still looking after this mod or should we consider it abandoned?

I have created a patch (see http://drupal.org/node/1829016#comment-7229766) for the dev version to make it work on my computer without warnings and errors. Please test it and lets try to get these changes into the recommended version.

I am setting this issue as fixed, as the original report has been fixed in the development snapshot. For the notice errors in the development snapshot code, see #1829016: Configuration form won't store changes.
