These are loading from cloudflare in your case, if they are slow to load, look to the source, in this case cloudflare for speed issues with loading them. 
However, those are all cached in the browser so they are only loaded once per user, once they are loaded they are served from the browser cache.  
Are you seeing actual speed issues with your site or trying to make speed test sites happy?  

There is not an option for this. Unvalidated members no longer have a group like they did in 3.x

Please submit a ticket for support. 

Hello,
This is not an SQL injection - he supplied a username that was longer than we are able to store in the login log column. We'll address this as a bug, but there's no security concern here.
Thanks

🙂 
 
 
 

If I recall correctly, PHP 7.4 is not fully supported until our 4.5 version is released.

This must be THE very patient Rhett reminding me I'd have known this if I had upgraded the software even once between 2011 and now?  :p  Yes, I've learned my lesson! 
Since that plug in shows anon users, my paying users did not like it. So, I use it on Pages to entice Guests to register with a 6 hour cut off and in ascending order, which shows a ton of users and makes it confusing enough (listing and time wise) for paying users to be okay with it.  I use the Who's Online on the Forum because it's accurate and they want to know who's online and how many anon, etc.. I did have to explain and literally demonstrate to the anon users that they can see themselves on the Forum lists, but are anon to everyone else. This wasn't an issue with the Who's Online from years ago.
Now I'm working on why my Google Ads are not working. Javascript disabled...?
 

If you are using third party items you will need to wait for each one to be updated for 4.5 or confirmed the current version is working with 4.5.  Since 4.5 hasn't been released at this point, nobody is working on updates just yet, once developers get their hands on beta versions they can start developing and testing for any needed changes. 
If you are not using any third party items, then once the final version is released, you can upgrade without issue!  
If you have a very large site or items of concern, and are self hosted, you can always do a test install to test your upgrade process and third party items before doing your live community if needed. 
The final golden rule, always do a backup of the database and file system before upgrades, things can sometimes go wrong, so it's always nice to have a quick restore as an option rather than freaking out if your community is troubled with an upgrade issue.

We currently have this message showing regardless of license status for communities that may be affected (it looks like the OP's screenshot was taken after the patch was applied, so it wasn't visible).. 

 
This isn't a 'backlog' as such, it's an error log showing emails that have failed to send.. These emails will not be sent unless you manually click the resend button on the right. The error log records are pruned after a period of time (30 days by default). You can safely leave those record if you wish and they will remove themselves.

You could search for all members in a group and then choose to delete all of those users. It would take some time for this to happen via the background tasks but I would strongly discourage you from trying to do this in the database directly (there are tons and tons of tables that would need to be considered).
Just search for all users in the "Members" group and choose to delete the results. Repeat for each group except admins, and then delete any admin accounts except yours one by one.

This is a built in item,  In your admincp live search, search for analytics, open the link of "Enable analytics tracking code" select "other" and paste in your code.
 
 

Support helped me resolve this - I needed to manually flush out the cache which in my case was in Redis not the datastore folder.

Thanks!

They do not auto install, to force this, download a full set of files from the client area, extract those to your computer and upload to your site, this will ensure you have all the latest files and patches, ensure that when uploading you overwrite all existing files.
 

This is actually built into almost all browsers by default, CMD + on mac and ALT + on windows, it retains memory based on the site as well, so you can have your users adjust this as needed for their sites they use.
 
Mac - Cmd' + '+' (plus) to zoom in
Win - Ctrl' + '+' (plus) to zoom in
You can manually edit the theme, however there would be many areas to edit as there is different text size in many places. 
 
 

Either one,  it makes no difference, it's all preference. 

It looks like they may have upgraded you to mysql 8.x and the old version you are on will not work with that, you need to have them downgrade that to mysql 5.6 if you want the old version to function.  Again this may not be 100% accurate, but a quick (blind) look at the site and it looks like that may be the case.
 
 

If you make sure you have the latest patch (AdminCP > Support > Something isn't working > click 'apply patch' if it says one is available) this issue will automatically resolve itself when you visit the forums listing in the AdminCP.

We will be releasing a patch or update soon that disables the email feature altogether. In 4.5, the email share function utilizes the sender's own mail client (mailto - for you nerdy types) and does not pass through the software.
