I don't know what version of b2 you have but do check that you have the fie .arcdir.php in the skin folder

Ver 1.9.2

That file [u]does[/u] exist in the SKINS folder.

In skins/custom/_archives.php I set $archive_limit = 30 , but that made no difference to display of 12 entries.

OK,

Thanks for pointing me at the arcdir member...now I have sussed it...just amended main.php archive section to....

<?php
// -------------------------- ARCHIVES INCLUDED HERE -----------------------------
// Call the Archives plugin:
$Plugins->call_by_code( 'evo_Arch', array( 'title'=>'',
'block_start'=>'',
'block_end'=>'',
'limit'=>'',
'more_link'=>'' ) );
// -------------------------------- END OF ARCHIVES ----------------------------------
?>
