Answer 1

Hello @vijaysumit,

Please replace this line of code:

$countslugs = @count($categoryslugs);

with this one:

$countslugs = $categoryslugs ? count($categoryslugs) : 0;

in line 138 at qa-include/pages/unanswered.php

Since PHP 8 is been used, these other fixes are also recommended:

• How could I fix HTTP 500 error shown after enabling RSS feeds for search results?
• Why can’t users upload their avatars?
• Unable to add category as superadmin

If you enable the reCAPTCHA plugin, then this error might be thrown:

mod_fcgid: stderr: PHP Fatal error:  Uncaught TypeError: array_key_exists(): Argument #2 ($array) must be of type array, null given in /www/qa-include/app/captcha.php:98

which can be fixed by replacing:

'error' => @array_key_exists('captcha', $errors) ? qa_lang_html('misc/captcha_error') : null,

with

'error' => isset($errors['captcha']) ? qa_lang_html('misc/captcha_error') : null,

in line 98 at qa-include/app/captcha.php

I hope it helps.

Comments

Thank you :) Still errors exists :((

I think there’s one line of error log missing at the beginning, it describes where the actual error occurred. Could you please edit your comment and add it so that I can check it?

edited, thanks

Done, I’ve edited the answer. Please, try to reapply the reCAPTCHA change. This error was thrown because I used the wrong quotation marks ([‘’] instead of [''])
