Sounds like a bug in Elgg (Ref.).

Is there any way to bypass this?

The only way is to manually make changes to ElggInstaller when checking this step.

Can you use 'Developer tools' plugin to catch the error?

Switch on 'Enable error log' in the plugin's settings and reproduce your issue.

Now check out /admin/develop_tools/error_log

Because the log you provided doesn't clarify the details.

Check log

It means what it means.

Thanks. It has been solved by hosting service. When I asked what the problem was, they said that The relevant situation had occurred due to heavy PHP usage. There might be areas in my software that I need to optimize. And added they recommend that you have a professional webmaster or software developer review it.

right now when someone visits my page all they see is a login screen

Seems, you've enabled 'Restrict pages to logged-in users' option (aka 'Walled garden' mode).

So your front page will always limited with login form. You can only change the background image there.

For non-walled garden case use these plugins to change your front page:

https://elgg.org/plugins/3265187

https://elgg.org/plugins/3332885

You can use the bundle "Front Page Demo" plugin (or custom_index) for configuring various elements on the homepage. Alternatively you can find community plugins like the Widget Manager in which you can enable a custom index where you can freely configure a homepage layout with widgets

You need to override some files in your custom plugin:

\views\default\object\comment.php
\views\default\object\elements\full.php
\views\default\object\elements\full\header.php
\views\default\object\elements\summary.php
\views\default\object\elements\summary\metadata.php

Edit \mod\your_plugin\views\default\object\comment.php to provide the new views:

\mod\your_plugin\views\default\object\comment\elements\full.php
\mod\your_plugin\views\default\object\comment\elements\summary.php

Edit these new views to provide another new views:

\mod\your_plugin\views\default\object\comment\elements\full\header.php
\mod\your_plugin\views\default\object\comment\elements\summary\metadata.php

Your goal is to extract elgg_view_menu('social') from

\mod\your_plugin\views\default\object\comment\elements\summary\metadata.php

and place it in a new view, e.g.

\mod\your_plugin\views\default\object\comment\elements\summary\social.php

Then you can place this social.php view to \mod\your_plugin\views\default\object\comment.php under $params['content'] for:

echo elgg_view('object/comment/elements/full', $params);

and

echo elgg_view('object/comment/elements/summary', $params);

Some CSS magic then and done ;)

Thanks for the help. It worked :)
