Fatal error: Call to undefined function panels_print_layout()

For now, copy/paste this into your panels.module file:

function panels_print_layout($id, $content) {
  ctools_include('display-render', 'panels');
  ctools_include('plugins', 'panels');
  $layout = panels_get_layout($id);
  if (!$layout) {
    return;
  }

  return panels_render_layout($layout, $content);
}

Do not include the <?php or ?> tags.

We will figure out a better, more permanent solution shortly.

Thanks, sdboyer. I took a risky chance and upgraded my live site without testing first and ouch! I do have a backup but this works much nicer than reverting to the insecure version. :)

Thanks! This fixed the error for me as well. Great timing!

Thank you! This seems to fix the error just fine for me.

Thank you, sdboyer.

I get a similar error but with "panels_load_include()":

Fatal error: Call to undefined function panels_load_include() in home/000/public_html/sites/all/modules/views_bonus/panels/views_bonus_panels.module on line 18

What change, as in #1, I need to make to "panels.module" to solve this issue?!

Note: I have latest dev versions of Panels & Ctools downloaded yesterday.

I'm not sure what's going on...the first time I tried the fix in #1 it worked fine and displayed my views_bonus_pack panels normally. But, I wanted to retest before putting it on my live server. And now I cannot get my views_bonus_pack panels to display. I upgrade to Panels 6.x-3.4, then add the patch in #1, and it no longer displays any errors, but simply does not display my views on the page.

problem solved- I just had not upgraded ctools yet, where I had the 1st time. Fix in #1 seems to be working now.

I have updated all modules and is then received this error. I copied the code at the end of "panels.module", but now receive this error: Parse error: syntax error, unexpected '<' in /home/xxxxx/public_html/xxxxx/sites/all/modules/panels/panels.module on line 1047
What can I do about this?

When pasting the code, do not include the <?php or ?> tags.

I did, but still errors.

Well, the error you got suggests there is a stray < at the line that it mentions. It's hard to tell what you actually did, but my guess is cut & paste error.

I delete everything and started from the start again, and now it seems to work well. But I having trouble entering blocks in Panels. It stands and loads and loads, until I re-load the page. Then I can see the block and save it. All other things seem to be working fine.
Thank you for your help.

See http://drupal.org/node/804198 for that one

OK, the function has been restored in panels.module (though it's been marked deprecated), so this'll be included in the patchup release I'm making presently.

I had the same problem, took down most of my site. My fix was to revert to Panels 3.3.

It seems this function can't be deprecated since other modules (presumably Views) rely on it.
