Hi,
Popen is core PHP function, you need that function to be enabled if you want to index content of pdf files. If your server doesn't support that function, you can disable the plugin: Edocman PDF Indexer to avoid this matter

I have raised a ticket on this and had the same answer.

We have enabled popen function on the server and still get the same error message.

Turning off indexer plugin is OK as a short term fix but we need our docuements indexing, otherwise our users will not be able to search for them!!

Please can we find a better solution?

Thanks
Alison

Hi Alison,
Please update the ticket and provide your site url with super admin account. I will have deeper checking for you
Thanks

I already did on ticket 125777 (you will need to reopen it please).

Be aware that indexer is turned off, you will need to turn it back on to recreate the problem.
Thanks

Hi Alison,
I am waiting for your response
Thanks
