PHP upgrade to 8.1 crashed my site

[FragaCampos]

Greetings.

Two days ago, my webserver upgraded PHP to version 8.1, which broke my site.
Because of that, they had to revert to PHP 7.4, but that broke my search (for what I've seen so far).
From what I read here, I should recreate my search index, but that didn't solve the problem.

This is what I see when I do a search:


And this is what I have in settings (I created a custom index, to no avail, and I have that message saying I can't create a full index, which was the option I had for years):



What should I do now?

2.0.19 supports php 8.0, it will run in 8.1 but log errors.  Anything earlier than 2.0.19 supports up to php 7.4.  If you're running 2.0.19 and forum crashed, it's most likely due to a mod that doesn't work in php 8.x.  You can upload a clean set of 2.0.19 files, that will remove all mods and customizations, and upgrade php to 8.0.  See if that fixes the problem.  Best bet is to upgrade forum to current version 2.1.4.

So, could you confirm you are actually on 2.0?
The error makes me think you are not, and are in fact on 1.1. since I think that file belongs to a 1.1 mod.
SMF Search Enhancement Mod

EDIT: I'm stupid, it's stated in your screenshot - you are on 2.0, and therefore you probably have the 2.0 version of this mod that no longer exists for some reason. Anyways, uninstalling this mod would be my first step in solving the issue.

Thanks!
You were right, uninstalling this mod solved the problem. 
So, if this mod was the problem, can I ask to upgrade again to 8.1 to see if the problem went away?

[Aleksi "Lex" Kilpinen]

You can try, but 2.0 does not fully support 8.1 so if you have the option to stay on 8.0 instead, I would recommend that, or upgrading to SMF 2.1
You will be forced to upgrade to 2.1 at some point though, if your host keeps updating PHP like that.

The problem with upgrading to 2.1 is my theme...
I know I have to do it some day, but I prefer not to think about it right know

You nedc to think about it sooner rather than later,  since you are going to see more and more incompabilities popping up

Yah, that's really the main problem.
I guess I really need to start reserving the time to do it...

Anyway, for some reason, my forum doesn't run with PHP 8.0. I tried it via cPanel, but I had to revert back to 7.4.

I found two more problems, probably related to other mods, but that only appeared after this upgrade attempt.
The first one is this, which appears when I click on a main menu button, which points to a static page:


The other one is this, which appears when clicking on another main menu button, a tops page:


Any thoughts? Should I open a topic for each of these issues?

[Kindred]

Well, how did you add the menu link?

The second error would appear to be related to your post ratings mod

[FragaCampos]

Well, how did you add the menu link?

I added it in Subs.php, with this code:

Code Select Expand

'donativos' => array(
                'title' => $txt['donativos'],
                'href' => $scripturl . '?spage=donativos',
                'show' => !$user_info['is_guest'],
                'sub_buttons' => array(
                ),

The second error would appear to be related to your post ratings mod

This was working without problems before. 
This is the code I have in that area mentioned by the error above. Is there anything I can change?

Code Select Expand

    // Highest User Ratings Query...
    $userrated_result = $smcFunc['db_query']('', '
        SELECT
            COUNT(mr.id_msg) AS total_votes, m.id_member, IFNULL(mem.real_name, mem.member_name) AS user_name
            FROM {db_prefix}topics AS t
            INNER JOIN {db_prefix}messages AS m ON (m.id_topic = t.id_topic AND m.ratings_enabled = {int:is_one} AND m.rating != {int:is_zero}' . (empty($modSettings['post_ratings_type']) && empty($modSettings['post_ratings_first_post']) ? ' AND m.id_msg != t.id_first_msg' : '') . ')
            INNER JOIN {db_prefix}message_ratings AS mr ON (mr.id_msg = m.id_msg' . $user_days_query . ')
            INNER JOIN {db_prefix}members AS mem ON (mem.id_member = m.id_member)
            WHERE t.is_ratings = {int:is_one} AND t.approved = {int:is_one}' . (empty($modSettings['post_ratings_stats_locked_topics']) ? ' AND t.locked = {int:is_zero}' : '') . '
            GROUP BY m.id_member
            ORDER BY total_votes DESC, mr.date ASC
            LIMIT {int:limit}',
        array(
            'is_one' => 1,
            'is_zero' => 0,
            'limit' => !empty($modSettings['post_ratings_stats_highestusers_limit']) ? (int) $modSettings['post_ratings_stats_highestusers_limit'] : 10,
        )
    );

....   ok, and what is the text string that you have defined $txt['donativos'] to be?


Yeah..postratings mod was last updated for 2.0.3.  You can be fairly certain that it does not support modern php or possiubly mySQL versions...   the solution would be to ask in the post ratings mod support thread or uninstall the mod

I have it defined in index.portuguese_pt-utf8.php

Code Select Expand

$txt['donativos'] = 'Donativos';

So, if the mod was functioning before, it means the forum was in a previous version of PHP 7.4?
Thanks anyway. I'll ask for help on the postratings mod page.

You need to have thr text string defined in English too, I believe

[FragaCampos]

Is this still a problem?

[FragaCampos]

It is.

[Kindred]

Well, honestly,  the only real solution is upgrading to 2.1.x

[Sir Osis of Liver]

2.0.19 supports php 8.0, it will run in 8.1 but log errors.

If upgrade to php 8.1 crashed the forum, that's most likely due to a mod that won't run in 8.1.  You can clean up the 2.0 install by uploading clean files and remove hooks with repair_settings, that will remove all mods and forum should run normally.
