Dependency Level of a plugin

Wed, 17 Dec 2025 16:54:03 +0000

Currently, in the metadata.json, there is following feild:

"load_order": "after_db_init" or "load_order": "before_db_init"

which indicates, when should load this plugin - is it before db initialisation or after db initialisation.

Let's assume following situation:

if pluginA defined a function F, and pluginB needs to use that function. That means PluginB is depends upon pluginA. However, there is no way in the current q2a, to define this dependency level.

So, we have two options:

PluginA needs to be loaded before pluginB - This is based on the names of the plugins and order is not correctly predicted.
Redeclare the same function with similar logic - this will leads to inconsistency if pluginA modified the function F.

To avoid this, I have added following feild in the metadata.json

"dependency_level": 2, - which indicates, the loading level of plugin. (Lower the dependency number, loads earlier.)

Hence, first all the dependency_level=1 plugins will be loaded, after that dependency_level=2 plugins will be loaded.

The code fix is available at https://github.com/q2a/question2answer/pull/1011/commits/182041865f7003f20d4e8c64d1d82ce7a5f7b7bc

Option to log out from all devices

Wed, 30 Apr 2025 13:14:31 +0000

If we've logged into our account on multiple devices, is there an option to log out from all of them at once—especially in cases like a password change? If not, could such a feature be added? It would be extremely helpful in situations where a user's login credentials may be compromised.

A similar query ( https://www.question2answer.org/qa/90765/logout-from-all-devices-after-password-change-q2a ) was asked few years back but no response on that question.

Please Help I have a white screen and don't know why.

Sun, 15 Sep 2024 04:09:34 +0000

Hello All,

I could use some help. I uploaded the files for q2a and edit the qa-config.php file. Renamed it and the .htaccess. However, I am getting a white screen. I am not getting any errors any where to tell me what is going on. The server requirements meet the requirements for q2a. Maybe I am missing something. Could anyone suggest something that I could look for?

Suggestion: Community guidelines require that questions include specific information

Thu, 31 Aug 2023 13:46:42 +0000

I have noticed that many people post questions here, but they don't seem to provide enough information for a proper solution. It's important to understand that the developers trying to help can only do so much without specific details. Please value their time, effort, and support by providing as much detail as possible when asking questions. If a question doesn't give enough information, it may need to be closed. Creating guidelines for posting questions is also advisable.

Mon, 21 Aug 2023 12:25:28 +0000

I'm currently updating themes and plugins. However, when I tried to post my first question, I received a notice/error saying, "database query failed when generating this page." Upon checking the error logs, I found a message indicating that there may be an issue with the Core. Despite this, the content (question) was successfully inserted.

"NOTICE: PHP message: PHP Question2Answer MySQL query error 1292: Truncated incorrect INTEGER value: '' - Query: INSERT INTO qa_options (title, content) VALUES ("cache_qcount", 1) ON DUPLICATE KEY UPDATE content = VALUES(content) + CAST(content AS UNSIGNED)"

Does anyone have an idea if the issue is related to the version of the database, PHP, or core? Or should I investigate my theme code further?

Q2A script not adding + sign in URLs with whitespace in the tags or usernames. Please help to fix

Mon, 13 Mar 2023 14:30:35 +0000

Previously, my website was functioning correctly, but now I am unable to access URLs with whitespace in the tags or usernames. It appears that the Q2A script is not replacing whitespace with a plus sign (+) in the tag URLs, causing a 'Forbidden' error when trying to access those pages. How can I fix this issue?

UPDATE:
I found that htaccess option in url structure is not OK but I doubt how it automatically changed from OK to blank and I have not even changed anything on server side.

Mod rewrite options is already enabled and htaccess file is also already available with default settings.

But still first URL structure is not OK and I have the problem accessing the URL mentioned above.

Please anyone help me fix the issue.

URL Structure for Q2A website hosted in wordpress website directory

Sat, 04 Feb 2023 09:32:31 +0000

Hello,

I installed q2a on my wordpress website subdirectory (htdocs) example.com/q/ and working url structure is /?qa=123/why-do-birds-sing

I want to change url structure to example.com/q/123/why-do-birds-sing [q2a general setting > option 1] but when i select first option and open example.com/q/123/why-do-birds-sing url then it's showing 404 error of wordpress theme 404 page.

My wordpress website is installed on UBUNTU server with Nginx.

I didn't want to have a common database for wordpress site and q2a site so that is why i want to host q2a on separate database with wordpress website.

When i try to move q2a outsite htdocs folder usinf FTP then it's showing wordpress theme 404 page.

Note - There are page rules on my main wordpress website which redirect all urls to home page or on specific page if url have ? symbol.

What should i do to have plain url structure (Defauld Q2A first option in general setting).

.htaccess file is -

Options -Indexes
DirectoryIndex index.php
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} libwww-perl.*
RewriteRule .* – [F,L]
#RewriteBase /
RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
RewriteRule . %1/%2 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ index.php?qa-rewrite=$0&%{QUERY_STRING} [L]
</IfModule>

Empty output after HTML tag closure - '', '');

I've always wondered if these empty outputs were made by design, or something was deleted from there and just forgotten to be removed.

Example:

$this->output('</div> ', '');
