Can't login to Modx manager

vreerapzat · March 5, 2024, 1:38pm

hi,

I have a modx 2.7.3 on php 7.3
I can’t login to the manager anymore, and I am sure that the logins are correct.
After I click on “login”, the screen flickers and I only see empty login fields with no error.

I checked that all the paths are correct in config & I also cleared the cache folder.
For the rest the website is working correctly in the front-end.
What is really bizarre, I have a similar site on that server, and there I can login correctly.
The site has migrated a while ago from another server, but this might not be the issue I think.

I enabled debug, and I go this debug log. How can I fix this please ?

It seems that a fatal error occurs, when the code tries to run a plugin (because the parser is null for some reason).

You could try to (temporarily) disable all the plugins and check if you can login again:

In the database table modx_site_plugins set the column disabled to 1
Clear the cache folder (core/cache)

Also maybe check the system settings parser_class (and parser_class_path) in the database table modx_system_settings. Do you use another parser than the MODX parser? Is the path correct?

hi Harry,

Thank you for your insightful tips. I applied them both, with no results unfortunately.

Do you have any tips on how I could further fix this ?

Can I give you server access and pay you to fix this ? I have lots of automatic server back-ups, so restoring to the previous version is done with one click.

Thanks

Is the error message still the same?
Are you using the default MODX parser (modParser)?

No.

When I’ve seen similar symptoms, it meant that I was actually logged in to the Manager, but the redirection didn’t take. Next time, see if you can go directly to a manager page by putting something like this in the Browser’s address bar:

yoursite.com/manager/?a=resource/update&id=1

Adjust as necessary for your site (actual name of your site, the manager name, and the ID of a real doc at the end).

Thank you Bob for your contribution.In my case this did not work.

I set debug_level to 4, and then looked at core/cache/logs/error.log.

I found that something is missing in the database which is vital for logging in:

I have a print-out of the whole setting

hi Harry, I am not using the standard modxParser.
Here you can see all the settings, this could be useful for your investigation:

thank you so much!

halftrainedharry · March 6, 2024, 8:26am

Is there no table modx_session in your database?

vreerapzat · March 7, 2024, 8:01am

thank you so much, you’re a genius indeed …
Sometimes the solution is staring us right in the face

I just added that modx_session in the database, and now I can login again ! Yay !

CREATE TABLE `modx_session` (
  `id` varchar(255) NOT NULL DEFAULT '',
  `access` int(20) UNSIGNED NOT NULL,
  `data` mediumtext DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_swedish_ci;
