My website stopped working due to a CiviCRM problem, all I see is: "CiviCRM does not have permission to write temp files in ...wp/wp-content/uploads/civicrm/templates_c/en_US/,exiting"
My hosting service may have recently updated to php 7.4. Seeing old solutions to this problem, I deleted all the folders in wp/wp-content/uploads/civicrm/templates_c/en_US/ but left .htaccess unchanged. That did not solve the problem. Should I delete everything in .../uploads/civicrm/templates_c/ Has anybody had this problem and fixed it?
