I recently migrated from v2 to v3 and am strangely enough, having the exact same issue I did 10 years ago, the last time I upgraded.  I managed to dig up an old thread I had posted in 2005 with the same situation.  Essentially it's that all the abstracts seem to no longer be displayed with their line breaks/paragraphs.  When editing the field, the paragraphs are there but they are not displayed on the summary page.

I've tried the fix from 10 years ago but as you might expect, that did not work.  I tried sticking the code snippet into eprint_field.pl.

Any help would be greatly appreciated thanks.

Hmm. I'm not sure why that changed. The default rendering for fields of type "longtext" appears to just turn them into a single block of text now.

It's easily worked around however by adding the a rendering parameter to the "abstract" field config in ArchiveMetadataFieldsConfig.pm:
----------------------
{ name => "abstract", input_rows => 10, type => "longtext", render_single_value=>sub {
    my( $session, $field, $value ) = @_;

   my @paras = split( /\r\n\r\n|\r\r|\n\n/ , $value );

   my $frag = $session->make_doc_fragment();
   foreach( @paras )
   {
       my $p = $session->make_element( 
           "p", 
           class=>$self->{name}."_paragraph" );
       $p->appendChild( $session->make_text( $_ ) );
       $frag->appendChild( $p );
   }
   return $frag;
} 
},
------------------
and restart apache and MAKE SURE IT WORKS,as i've just cut and pasted the code
then run generate_abstracts to fix the ones which are wrong.

The "render" paramters only effect how a value is converted to XHTML, so they can
safely be played with without effecting the underlying data.

Hi Folks, 

I migrated an EPrints archive from v2 to v2.3.7 on a new server.  Everything seems in order except for the linefeeds and paragraphs in the Abstract field.  In the old version they show up fine, but in the new version it is all one paragraph. 

Anyone know how I might be able to fix this?   

I should mention that when I edit the eprint, the paragraphs are there, they just don't show up when you view it. 

Thanks in advance, 
Mike.
