Hi,

I just tried to enable the latest version of OL on a fresh installation of drupal 7.15 after enabling the required modules: views (7.x-3.3) and Chaos tools (7.x-1.1). This resulted in the following error message:
Fatal error: Cannot redeclare drupal_error_levels() in /customers/2/8/2/[mysite]/httpd.www/includes/errors.inc on line 31
I hope that anybody could provide me with some help.

Thank you very much in advance.

Can you try to give me more informations ?
If it says that it cannot redeclare the function, it should display the two places where it's defined.
Can you have a look at the error log ?

Thanks

Dear Pol,

Thank you very much for your fast answer and I am sorry for my slow reply.
When I try to enable the OL module I get the error message as described - but there is no entry in the
"Recent log messages" about this. I suspect that this is what you mean by 'error log' if not, may I kindly ask you where to find the appropriate 'error log' since I could not find any other error log elsewhere. I am new to drupal so my technical abilities are rather limited.
By the ways, the error message described, only appears when switching on the 'php error messaging' via my host (one.com) otherwise I just get a blank screen.

Thank you once again for your answer - I appreciate your help a lot and am happy to provide you with all the information you would need.

All best

I get an error message too in my site.
This message appear in admin/modules too, while module is present in list.
There are no messages in the system log.
So, in dev version no error!

Is this still a problem in the latest dev?

I solved the issue by simply getting a new webhotel - I could not manage to get the site running via one.com
(@mgifford: after the change everything seems to work so I did not try the dev version)
Due to DenisVS's comments, I will not close the issue.
