# Plugin Conflict?

 * Although the PDF plugin 2.0.2 works just fine, I encounter problems with 2 other
   plugins and it’s pointing towards the PDF plugin. Text is shown between brackets.
 * Plugin: Cardgate (payment service provider)
    “<br /> <b>Warning</b>: Invalid 
   argument supplied for foreach() in <b>/home/cbdplein/public_html/wp-content/plugins/
   woocommerce-pdf-invoices-packing-slips/includes/class-wcpdf-documents.php</b>
   on line <b>72</b&” This is the full message, although it seems to be incomplete.
   This message is received on the Cardgate backend. Data (payment status etc) in
   Woocommerce is correct though.
 * Plugin: e-Boekhouden.nl (accounting)
    “Fatal error: Call to undefined method 
   WooCommerce_PDF_Invoices::load_classes() in /home/cbdplein/public_html/wp-content/
   plugins/e-Boekhouden.nl/includes/lists/3x/eboekhouden-order-list-table.php on
   line 130” The plugin can’t complete the order list which is needed to export 
   data to the accounting program.
 * Woocommerce and all plugins are latest versions. Any idea what’s the problem 
   and how it can be solved?

 * Hi! Thanks for reporting. I have [added a fix](https://github.com/wpovernight/woocommerce-pdf-invoices-packing-slips/commit/478792417c3b075c6707ff3b9f09cb619f164232)
   that prevents the Cardgate warning, although I’m not sure why it was triggered
   in the first place. You may want to test whether invoice attachments still work
   for orders placed with that gateway.
 * As for the second error, you will need to contact the e-Boekhouden.nl developers,
   it looks like the plugin is not compatible with 2.0 yet. I wasn’t aware of this
   integration or I would have given them a heads up during the beta.
 * I will include the fix for the Cardgate warning in the next 2.0.3 update (probably
   monday).

 * Great! Many thanks Ewout for the swift reply and fix.
 * I’ll inform the e-boekhouden developers about this issue.

 * Update:
 * The Cardgate fix did the trick and no error messages appear anymore 🙂
 * The e-boekhouden plugin developers have been notified. They are looking into 
   it and will contact me once resolved or in case of questions/remarks.
 * Thanks, JJ

 * Just to let you know that I have pushed a plugin update (2.0.3) that includes
   this fix.
 * I have also contacted e-Boekhouden.nl with suggestions on how to make this work
   with both the latest and older versions of the plugin. Another customer contacted
   me telling that e-Boekhouden suggested to turn off the plugin during export which
   I don’t think is a very good solution, so I hope they will use my suggestions
   instead 🙂
 * Closing this thread for now – let me know if any other issues arise!

 * The update runs like a charm, thanks 🙂
 * e-Boekhouden suggested me the same procedure. Not an ideal solution indeed, so
   hopefully they’ll update their plugin soon.
 * Cheers,

 * Update from e-Boekhouden plugin
 * Today they sent me an update (v2.0.8) for testing and it works just fine. No 
   conflicts and no workaround needed anymore.
