I can get the elgg token from somewhere else

I don't think it will be easy.

It's better to use the method of deleting the entity from the database.

Another way to find out the widget GUID is to look at the source code. (Ctrl+I to open Devtools/Inspector in the browser).

There you'll find something like this:

<div id="elgg-widget-446" class="elgg-module elgg-module-widget elgg-widget-instance-image_slider elgg-state-draggable elgg-module-widget"

where 446 is GUID.

Thank you Nikolai. I shall try!

Kind Regards.

UPDATE/ First of all, correction of problem statement: Almost-whitescreen is NOT created by the image slider widget. It is created by hypeScraper being hanged by an URL posted by a user. I cannot update the original post, hence here.

I was too much consumed by the "image slider" and three vertical dots displayed on otherwise all-whitescreen and the connection attempt to flexslider.woothemes.com in the status bar. Regardless of this, I should have checked the Apache error.log. A typical RTFL case. I am sorry for the wrong pointers...

I identified the URL posted by a user which made hypeScraper hang. After deleting that post, index screen displayed perfectly. I have no idea why some (albeit very rare) URLs cause white screen with hypeScraper.

I assume that you're using Apache as the webserver on your VPS.

Maybe some/all of the modifications made in de .htaccess aren't allowed by Apache.

In the vhost configuration of Apache make sure you have the following in your section where you configure the Elgg vhost.

<Directory "/path/to/elgg/installation">
    AllowOverride All
    Require all granted
</Directory>

Also check the Apache error logs they may give you a hint what's wrong

1. Website speed depends on your webhosting. If you think that the site is too slow, try to upgrade to a faster server.

2. Not possible with the login you gave us here, as amitdas is not an admin.

3. What kind of image? And where?

4. See 1.

5. See 3.

6. The site works fine for me. For a full website test, provide admin username and password here.*

*Don't!
