    <p>I'm having a really, really, really weird problem on my vBulletin board using Facebook's Like Button. In my thread template I'm using the following code, which is located inside body tag:</p> <pre><code>&lt;td class="vbs_forumdata alt1"&gt; &lt;div id="fb-root"&gt;&lt;/div&gt; &lt;script type="text/javascript"&gt;(function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(d.getElementById(id))return;js=d.createElement(s);js.id=id;js.src="//connect.facebook.net/en_US/all.js#xfbml=1";fjs.parentNode.insertBefore(js,fjs)})(document,"script","facebook-jssdk");&lt;/script&gt; &lt;div id="thread_sharing_content_facebook"&gt; &lt;div class="fb-like" data-href="{vb:raw sharingurl}" data-layout="button_count" data-send="false" data-show-faces="false" data-width="90"&gt;&lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;/td&gt; </code></pre> <p>As soon as the template is processed by the vBulletin engine, the variable {vb:raw sharingurl} is replaced by the thread's canonical URL, that looks like this:</p> <pre><code>http://MYDOMAIN/threads/THREADID-THREADTITLE </code></pre> <p>For example:</p> <pre><code>http://www.mydomain.com/threads/1-Hello-Community </code></pre> <p>Looking at the HTML source of a thread page, everything seems to work as intended:</p> <pre><code>&lt;td class="vbs_forumdata alt1"&gt; &lt;div id="fb-root"&gt;&lt;/div&gt; &lt;script type="text/javascript"&gt;(function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(d.getElementById(id))return;js=d.createElement(s);js.id=id;js.src="//connect.facebook.net/en_US/all.js#xfbml=1";fjs.parentNode.insertBefore(js,fjs)})(document,"script","facebook-jssdk");&lt;/script&gt; &lt;div id="thread_sharing_content_facebook"&gt; &lt;div class="fb-like" data-href="http://www.mydomain.com/threads/1-Hello-Community" data-layout="button_count" data-send="false" data-show-faces="false" data-width="90"&gt;&lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;/td&gt; </code></pre> <p>But then, if I click on the Like Button to share the thread page... here comes the drama:</p> <p><img src="https://i.stack.imgur.com/2EFtf.jpg" alt="Drama"></p> <p>The original URL of the thread page is messed up transformed into something like:</p> <pre><code>http://MYDOMAIN/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/THREADID-THREADTITLE </code></pre> <p>Anyone knows why I'm getting that strange problem? The only thing I was thinking about trying to figure it out by myself, is my htaccess file which contains some rewrite rules. It's almost the vBulletin default one... but, anyway, here they are:</p> <pre><code>RewriteEngine On RewriteBase / // Block Bad Bots RewriteCond %{HTTP_USER_AGENT} [...] RewriteRule ^.*$ - [F,L] RewriteCond %{HTTPS} !=on RewriteCond %{HTTP_HOST} !^www\..+$ [NC] RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L] RewriteCond %{REQUEST_FILENAME} -f [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^forums/.* forumdisplay.php [QSA] RewriteRule ^members/.* member.php [QSA] RewriteRule ^threads/.* showthread.php [QSA] RewriteCond %{REQUEST_FILENAME} -f [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^(?:(.*?)(?:/|$))(.*|$)$ $1.php?r=$2 [QSA] RewriteCond %{REQUEST_FILENAME} -f RewriteRule ^(.*)$ - [NC,L] RewriteRule ^(.*)$ - [R=404,L] </code></pre> <p><strong>EDIT: I tried using the Facebook URL debugger and...</strong></p> <p><em>Scrape Information</em></p> <pre><code>Response Code: 200 Fetched URL: http://www.mydomain.com/threads/1-Hello-Community Canonical URL: http://www.mydomain.com/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/1-Hello-Community </code></pre> <p><em>Critical Errors That Must Be Fixed</em></p> <pre><code>Could Not Follow Redirect Path: Using data from http://www.mydomain.com/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/1-Hello-Community because there was an error following the redirect path. </code></pre> <p><em>Errors That Must Be Fixed</em></p> <pre><code>Too Many Redirects: URL redirected too many times.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
