Deleted a tag, and now site is blank

pseudo-bash

Hi, I deleted a tag via admin -->administration, and the next thing I knew, there was an error flag at the bottom of the screen (the ones that say DEBUG). Instead of clicking it to read more, I refreshed the screen, and the site has now become a blank screen. I can't seem to figure out an efficient way of getting it up and running again.
Site is offgridauthor.com
Any help would be appreciated.

pseudo-bash

Sure wish I had read that error now. I wonder why the index.php doesn't load now?

Shouldn't be an issue, even if you delete all tags Flarum should still load.

Try the following (stop if any of these work):
1. Reload the page (CTRL+F5)
2. If blank, press F12 to bring up the web console. Not any error messages in the console and paste them in here.
3. If you can access the admin, try disabling the Tags extension.
4. Disable all the rest of the extensions.
5. If that doesn't work, check your server logs for any errors at the time you encounter blank pages and paste them in here.

The character encoding of the page must be declared in the document or in the transfer protocol. offgridauthor.com

Delete all the .js and .css files in your assets folder under Flarum's root. Then refresh.

pseudo-bash

I deleted the .js and .css files, no change.

jordanjay29

What is your server configuration? Does it meet Flarum's requirements?

pseudo-bash

yeah.
apache, php 559, ubuntu 14.04
is there a way to disable extensions without admin panel access?

jordanjay29

Via your database, sure. There's no command for it.

Speaking of which, can you run php flarum info for me in your flarum root and paste in the contents?

pseudo-bash

ok, i deleted "flarum-tags" via database, site comes up now.

jordanjay29

pseudo-bash Okay, disable it again.

Run
composer remove flarum/flarum-ext-tags

Then
composer require flarum/flarum-ext-tags

Try to re-enable it. If the problem persists, it might need a deeper inspection of what's going on.

pseudo-bash

and i re-enabled it, and broke again

pseudo-bash

ok, did as specified. site broke as before when re-enabling tags

I wonder if something is wrong with the tags table. It's possible it's corrupt on the database, or the contents are.

We could start with trying to repair the tags table (just that table) on your database.

pseudo-bash

OK, so i don't know if this is meaningful, but I checked/defrag/optimize/flushed the table, re-enabled in admin panel, and it went to the same blank screen. In the console, it shows error 500

GET
https://offgridauthor.com/admin#/extensions [HTTP/1.0 500 Internal Server Error 0ms]

jordanjay29

pseudo-bash In the console, it shows error 500

Now we're getting somewhere. Check your apache server logs for the 500 error at the time you accessed the page. We should get a more detailed description of what's going wrong.

pseudo-bash

Is that helpful?

pseudo-bash

139 to 147 ...
` $canForTag = function (Tag $tag) use ($user, $permission, $hasGlobalPermission) {
return ($hasGlobalPermission && ! $tag->is_restricted) || $user->hasPermission('tag'.$tag->id.'.'.$permission);
};

    foreach ($tags as $tag) {
        $can = $canForTag($tag);

        if ($can && $tag->parent_id) {
            $can = $canForTag($tag->parent);
