This mod has the effect of recording your own server as a guest on your forum which results in some odd behaviour such as listing your server in WOL and not having the ability to tag forum urls where guests do not have viewing permissions.

So, is this expected behaviour; should the code be modified to get around it? If so, how?

Yes, correct Rhodium, must have
PHP set for
allow_url_fopen = On

This mod is running okay now, once I made that PHP adjustment, in my 4.2.3 forum running PHP 5.6.30

Note: for any URLs that were not converted (during a period when you had allow_url_fopen = Off ), you must go back in and edit those posts AND remove the hyperlinks from the non-coverted URLs before re-saving the posts. Easiest way to do this is:
1. Click, Edit Post
2. Cut the URL that has not been converted
3. Paste it into a new browser window
4. Copy that URL that has been posted in that browser window
5. Paste the URL back into the post.
6. Save

Now the mod will have created the title for the post. For some reason, edit and save does nothing unless you remove the hyperlink from the URL in question (one that has not been converted).

This mod will not work with vb 4.2.5 IF running php 7. It will work under PhP 5.6

Quick replies while running this mod in php 7, go blank.

Running fine for me with 4.2.5 on PHP 7.1.

Have you made posts? Or threads? New ones I mean? Then try making a QUICK REPLY to the post, within the thread. Then try an Advanced Reply to the post, within the thread.

Also, I have a phpinfo.php file loaded in my directory to verify which exact version of PhP I am running, and an .htaccess file that was forcing PhP 5.6 for this directory only, for my vb4 forum only. I commented out the code in that .htaccess to revert to PhP 7, and that was when I determined these issues with this mod.

Issues I had were with PhP 7.0.18 if that makes a difference.

Yes; result below:

I don't know what your post above means. The URLs just direct me back to my own post within this thread. I meant, have you done that within your own vb4 forum that verifiably is running PhP 7 (such as verified with a phpinfo.pho file) and with this mod running.

It means it does work with PHP 7.1.

He's showing you examples: the notification email shows that he entered URLs and his post above demonstrates that they were converted to titles.

Well for whatever reasons, when I toggle this mod here, and this other mod (Automatic Tagger)
https://vborg.vbsupport.ru/showpost....&postcount=459
on and off, my vb 4 php 7 forum has issues, namely that posts made are invisible other than at most the title of a post on an advanced reply, and the issues go away when I disable those two mods.

These are the PhP errors from the error_log :

Those errors are with both mods running.

With autotagger off, but external title fetcher ON (under php 7):

I had conflicts with Automatic Tagger even before vBulletin 4.2.5 and with PHP 5.x.

What happens if you disable that one and keep Title Tag Fetcher installed?
