If you use dynamic URLs for your content import and your URL contains a + (plus) symbol e.g. 

https://some.org/technical+program/ExhibitorExport?openagent, you must replace the symbol with %2B for the CMS to read it correctly. The above URL would now look like https://some.org/technical%2Bprogram/ExhibitorExport?openagent

  1. Copy your URL into a text editing or note program
  2. Paste the URL 
  3. Replace the + with %2B
  4. Copy the corrected URL and paste into the CMS
