1.3-1 puts a '0' in the HEAD section before it is set up.

Okay, this is fixed in 1.3-3. http://drupal.org/node/302414

It was a dumb mistake... and I changed the condition to actually read the on/off switch in the module as the determination if to display the ShareThis code or not.

This means that the code should be inserted at the same time as when enabling the on/off switch.

function sharethis_init() {
if( variable_get('sharethis_type', 0) == 'sharethis_this') {
    drupal_set_html_head(variable_get('sharethis_sharethis_this_code', 0));
  }
}

I think this issue may fix the errors with duplicating shareThis items as well... it wasn't happening the first few times I tried it after upgrade.

Oh.. thanks for the bugfix.. i was wondering where and how this "0" popped in the HEAD of the site and what caused it.. sharethis! "0" :)

Crap... I'll take a look... I may need to physically uninstall the module for the test to properly work rather than just turning it off/on

This worked for me, but obviously it does not solve the issue, only prevents the zero from messing up the head section.

<?php
function sharethis_init() {
if( variable_get('sharethis_type', 0) == 'sharethis_this') {
    if ( variable_get('sharethis_sharethis_this_code', 0) != "0") {
            drupal_set_html_head(variable_get('sharethis_sharethis_this_code', 0));
    }
  }
}
?>

the variable_get('sharethis_sharethis_this_code', 0) should probably be changed to variable_get('sharethis_sharethis_this_code', '').

I found that version 6.x-1.3-3 is also leading to the same problem. Disabling the module clears the '0' from the left top corner of the page. Otherwise this zero is very persistent. When the page is refreshed or a new link is clicked the zero persists.

This is very annoying and I hope a solution is posted soon.

Thanks

Marked #333189: "0" in top of every page, can't control $head variable in page.tpl as a duplicate of this issue.

Marking issue for 6.x-1.x since this is still not fixed in 6.x-1.3-1 and up.
