Learn moreMODX 3.0 cleaned up a significant number of old system settings and changed the default value (for new installations) of some as well.
Removed¶
allow_tv_eval, the@EVALbinding is no longer supported for TVs for security reasons #13865forgot_login_email, password-reset mail now uses thelogin_forgot_emaillexicon and a reset link instead of emailing a password #13786. See forgot_login_emailcompress_js_max_files,manager_js_zlib_output_compression,manager_js_cache_file_locking,manager_js_cache_max_age,manager_js_document_rootwhich were related to the old dynamic manager js minification #13859, #14868editor_css_pathandeditor_css_selectorshave been removed #14843. TinyMCE and other third-party extras may still reference these settings and need to accommodate their absence.manager_language#13786, replaced by automatic language detection and on-the-fly switching in the manager #14046. Learn more about the manager language in 3.0resolve_hostnamesandserver_protocolhave been removed #14877. Deprecated settings from MODX Evolution.upload_flash, setupload_filesor theallowedFileTypeson the media source instead. #14252. Note: 3.0 additionally introducedupload_imagesandupload_media, but both were removed again in 3.1.0 #16349 — on current releases onlyupload_filesandallowedFileTypesremain.udperms_allowrootandwebpwdreminder_message#14841. Root resource creation uses thenew_document_in_rootpermission.webpwdreminder_messagewas an unused web-user password email template. See udperms_allowroot and webpwdreminder_message.cache_action_mapas the action map has been removed completely now that modAction is officially gone #14927filemanager_path,filemanager_path_relative,filemanager_url,filemanager_url_relative,rb_base_dir,rb_base_url,strip_image_paths,use_browserandfe_editor_lang. These mostly governed file-manager and RedBox paths; if you had a customfilemanager_pathorrb_base_dir, check your extras for the settings no longer being present after the upgrade.emailsubject,signupemail_message,websignupemail_message,manager_lang_attributeandtopmenu_subitems_max. The first three were mail templates/subjects: their text now comes from lexicons (signupemail_messageis still read with a lexicon fallback when a user account is created).manager_lang_attributeandtopmenu_subitems_maxwere unused leftovers.
Renamed¶
mail_smtp_prefix→mail_smtp_secure. Setup migrates the value on upgrade (3.0.0 upgrade script).upload_check_exists→upload_file_exists. There is no automatic migration for this one: check your site settings for the old key after upgrading.
Changed default values¶
Changed defaults below apply to fresh MODX 3 installations only. Upgrades keep the old values — consider applying the new ones to an existing site yourself.
