Blank pages for not logged in users

[slawomir...@gmail.com]

Hello,

I noticed, when I'm not logged in AtoM, I can't access to lower levels pages (in hierarchy tree). I can access only to Items.

For example:

Fond (Access denied - blank page)

|- Subfond (Access denied - blank page)

|-- Serie (Access denied - blank page)

|--- Subserie (Access denied - blank page)

|---- Item (Access granted - page with Item is displaying)

I thoungt that may be problem with my access rights settings, but I found nothing in the settings. So I checked Apache error.log:

error.log:

Could you get me a tip to solve the problem? Maybe you have already noticed similar problem?

Hi Slawomir, 

Can you tell us more about this installation? For example:

• What is the full version number of AtoM in Admin > Settings?
• I can see that you are using Apache instead of Nginx. What other changes have you made from the recommended installation instructions?
• What version of PHP and MySQL are you using?
• Have you upgraded from a previous version recently?
• Were these records originally created via the UI, or via import?
• What, if anything, have you tried so far to resolve the error?

I would suggest that you start with some of the common maintenance tasks listed on our Troubleshooting page (rebuild the nested set, generate slugs, clear cache, restart PHP-FPM, reindex, etc). You might also want to try running the SQL query on that page that can help check for data corruption - I'm wondering if some of these records are perhaps missing a publication status ID or similar. See: 

• https://www.accesstomemory.org/docs/latest/admin-manual/maintenance/troubleshooting/
  

Let us know what you find, and more about your environment, and hopefully we can offer further suggestions. 

Cheers,

Hi,

thank you for your reply. 

• AtoM is in "2.6.0 - 184" version. 
• Only change I made is Apache2 instead of nginx and AtoM directory (/var/www/html/atom).
• My server is Ubuntu Server 18.04 with PHP 7.2.24 and mysql 8.0.24.
• I haven't upgraded AtoM recently (but the problem was on older versions (2.5.4) too).
• The records (Fonds, Subfonds, (...), Items) was created in UI
• I tried to change and add some atributes, I compared the Fond with another working one and I tried to change some rights. I've changed the name and slug of Fond. None of it worked.

I did all of maintenance tasks, unfortunately, nothing improved the situation.

In AtoM we have 9 Fonds, and the problem touches only few Fonds (and lower levels in that Fonds, except Items and Parts).

Cheers,

Slawomir

Hi Slawomir, 

I think I've found the source of the issue, with some help from our team. I believe that you are encountering this bug: 

• https://projects.artefactual.com/issues/13402
  

This issue is fixed in the latest 2.6.4 AtoM release. 

If you are unable to upgrade at this time, then there are a couple of options. 

First, you can try disabling the carousel in Admin > Settings > Default page elements, and see if this allows the intermediary pages to load as expected. Of course, your users will not see a carousel indicating that digital objects are available at lower levels this way, but they will still be available in search/browse results, etc. 

Alternatively, because the change is minor, you could try updating the code locally in your AtoM instance. You can see the commit with the change here: 

• https://github.com/artefactual/atom/commit/92aab1b728872b7c41696aab3420f02a34da4fa2
  

If you decide to take this approach, I strongly recommend that you make a backup of your data first, and ideally test the change in a test instance before applying it to a production environment!

Hi,

thank you very much for help.

Turning carousel off works! At this moment I can't upgrade AtoM, but it's enough for us now. After upgrade, we just turn this option on.

One more time - thank you for helping me.

Best regards
