Cannot save a Panels flexible layout for reuse

Question

I wanted to save a flexible layout that I've already customized so that I can use it on the other pages on my site. After hitting the save button, I get a pop up with the following message:

Unable to complete operation. Fatal error in modules_dir/panels/plugins/layouts/flexible/flexible.inc on line 1741: Call to undefined function ctools_export_crud_load()

Versions

• Drupal 6.17
• Panels 6.x-3.7 C
• Ctools 6.x-1.7

Any idea what I might have done wrong during the installation? or anyone else encountered this problem?

Thanks!

Answer 1

Need to add the following snippet of code before the line in question above to fix the problem in saving the flexible layout:

ctools_include('export');

Kudos to merlinofchaos for helping me out here.

But the question still hasn't been really answered as to why I encountered the said error.
