    • (SOLVED) Blank screen on tiki-admin_categories.php after upgrade

    Posted by francis posts: 7 Canada

    Hello everyone,


    I have a problem that I can't resolve!

    Description : I installed Tiki 27.0 in October 2024, since then I have upgraded 2 times, first to 27.1 without any problems after upgrade. On April 12, I upgraded to version 27.2. This time, the only problem I encountered after checking all was the category administration do not displayed. It's simply a blank screen.

    I've checked the php.ini server memory is 128mg OK, I've checked the permissions on files OK.

    I've also redone the upgrade steps to see the error messages, but everything's OK.

    It's only the admin action (tiki-admin_categories.php) that doesn't work. Everything else works fine.

    Actually, I'm not find a solution for that. In last resort, I could go back to the previous version 27.1 and restore the database and the backup file.

    Note: the site is not currently online! It's still under development.

    Thank for your help

    Hello Francis,

    I'm using Tiki27 VSC release from gitlab for production sites since a few weeks now and it is working fine.

    I suggest you check your server error logs, this can point you a direction where to look.
    You mentioned the memory... try to increase the 128M (low limit IMO) v aklue to 256M or 384M and see what is happening.

    You can also use a daily release (very last version) of Tiki27: https://tiki.org/tar/lastiki_27-x.zip

    But, there are many details missing from you initial post and it is not really possible to help you without them. Contact me, I'll try to help.

    Hi Bernard,

    Thank you for your reply and support. Yesterday, I increased the memory in php.ini and set it to 256MB. Then I cleared the Tiki installation cache, refreshed the page, and unfortunately the result is the same.

    I repeated the exercise today with your suggestion of increasing it to 384MB, but without success. I still have the same result! I also tested with four different browsers, and the result is the same.

    Each time, I make sure to clear the Tiki cache! The result remains the same.
    Big thank

    apache 2.4.63

    Another try

    I downloaded the latest version, 27. But the upgrade went perfectly without any error messages. However, I still don't have access to the category administration. Always blank page!

    I'm going to roll back to version 27. That way, I can better determine the source of the problem.

    I made a new installation on a test site with version 27.2 lts. The problem does not occur on the test installation. I'm going to check all the parameters of the 2 installations to find the cause.

    I'll get back to you if I find the problem.

    Thank

    Hi,
    I resolved the problem accessing the category administration by deleting the content in the categories tables from the content database.

    TRUNCATE `tiki_categories`; TRUNCATE `tiki_categories_roles`; TRUNCATE `tiki_categories_roles_available`; TRUNCATE `tiki_categorized_objects`; TRUNCATE `tiki_category_objects`; TRUNCATE `tiki_category_sites`;

    This isn't the first or good solution I wanted, but it worked. Now I'll simply recreate the categories and then return to each article to assign them.

    I can't explain the reason. Perhaps the tables were corrupted during an upgrade or modification to the website.
    This was the only fast solution after many time to pass on it.


    Thank
