<p>Hi Fernando,</p>
<p>Having a look at a record where I can download the PDF where you have not had to do the trick with setting as a word document [1], i looks like you may be using the coversheets plugin.&nbsp; This does some clever (maybe not so clever) mod rewrites so that although
 you request the original uncoversheeted PDF URL, EPrints can see that he document has a coversheeted version and uses mod rewrite to do an invisible redirect (i.e. the URL does not change in your browser address bar) to the coversheeted version.&nbsp; I can quite
 believe that for some reason this coversheeted PDF is not generated and the mod rewrite sends you in an infinite loop and that is why your browser just sits there and nothing ever seems to happen.&nbsp; This would explain why you can get the PDF when you switch
 it to a word document as it will know this cannot have a coversheet generate version and therefore will not get stuck in a redirect loop.</p>
<p>I have had a look at your counter URL [2] that you are running a very old version of EPrints (3.1.3).&nbsp; I am not even sure you can run the coversheets plugin on this version of EPrints. (Although files.eprints.org suggest you can but maybe it works differently
 to more modern versions of EPrints).&nbsp; Normally coversheeting tasks get added to the event queue.&nbsp; The size of this queue does not get reported in your counter URL either, so I can tell whether the indexer has got stuck and caused this coversheet issue.&nbsp; You
 really need to look at you Apache access and error logs whilst making these requests to see what log messages you get.&nbsp; Also you should look at you Apache config files in:</p>
<p>EPRINTS_PATH/cfg/apache.conf</p>
<p>EPRINTS_PATH/cfg/apache/*.conf</p>
<p>EPRINTS_PATH/cfg/apache_ssl.conf</p>
<p>EPRINTS_PATH/cfg/apache_ssl/*.conf</p>
<p>EPRINTS_PATH/archives/ARCHIVE_NAME/cfg/apachevhost.conf (possibly some variation of this name)
<br>
</p>
<p>EPRINTS_PATH/archives/ARCHIVE_NAME/ssl/securevhost.conf <br>
</p>
<p>(EPRINTS_PATH typicallyis /opt/eprints3/ or /usr/share/eprints/ and ARCHIVE_NAME is whatever you chose, possibly etheses).<br>
</p>
<p>There may be something in one of this files that explain why there is a mod rewrite that causes an infinite redirect.&nbsp; Unfortunately, without having any access to look at these things it is very difficult to suggest what is going wrong.</p>
<p>Regards</p>
<p>David Newman<br>
