But the icons are in the folder and the folder exists. * i did not move the website, nor did resetting to defaults also does not resolve the issue. * pls advice. * Leaflet Maps Marker Warning: the setting for the marker shadow url ([http://mywebsite.com/wp-content/uploads/leaflet-maps-marker-icons](http://mywebsite.com/wp-content/uploads/leaflet-maps-marker-icons)) seems to be invalid. This can happen when you moved your WordPress installation from one server to another one. Please navigate to Settings / Map Defaults /“ Default values for marker icons” and update the option “Shadow URL”. If you do not know which values to enter, please reset all plugins options to their defaults * [http://wordpress.org/extend/plugins/leaflet-maps-marker/](http://wordpress.org/extend/plugins/leaflet-maps-marker/) Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [Robert Seyfriedsberger](https://wordpress.org/support/users/harmr/) * (@harmr) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-message-in-backend/#post-3381642) * Hi, the check for icons is based on the file readme-icons.txt in the marker icons folder (usually /wp-content/uploads/leaflet-maps-marker-icons/) – if this readme-file is not there, this warning is displayed. * ad Shadow url warning: might be due to the fact that your site is not visible for public yet. Please try for testing purposes to make your site available for a short time to see if this message is not visible anymore (which I guess) regards, Robert * Thread Starter [BackuPs](https://wordpress.org/support/users/backups/) * (@backups) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-message-in-backend/#post-3381647) * Hi Robert * Thanks for the fast reply. the file is there with this content. I cant make it visible. because the domain name does not exist. Its just a spoof to build the website and from there transfer to the real location. * i can even access the file on my system and open it by its link. * can you please add the ability to turn off those messages? I wont want them all the time in my backend. * thank you !!! * _ Leaflet Maps Marker plugin uses map icons from the Maps Icons Collection by Nicolas Mollet ([http://mapicons.nicolasmollet.com/](http://mapicons.nicolasmollet.com/)). By default, a preselection of about 100 icons (from more than 700 available icons) has been added to the plugin. On first activation of the plugin, the zip-file mapicons.zip gets unzipped into the directory \wp-content\uploads\leaflet-maps- marker-icons of your WordPress installation (note: you might have to enter your ftp-credentials once depending on your configuration) If you want to add more map icons, please download the desired icons from [http://mapicons.nicolasmollet.com/](http://mapicons.nicolasmollet.com/) and upload them to the directory \wp-content\uploads\leaflet-maps-marker-icons * PLEASE DO NOT DELETE THIS FILE FROM YOUR MARKER ICONS DIRECTORY AS IT IS USED TO CHECK IF INSTALLATION WAS SUCCESSFUL! * Thread Starter [BackuPs](https://wordpress.org/support/users/backups/) * (@backups) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-message-in-backend/#post-3381655) * Hi * you are using curl to check if the fileexists. Why not just use the php fileexists function like you do in the admin header.php? * if ( ! file_exists(LEAFLET_PLUGIN_ICONS_DIR .

You are cheching for the marker-shadow.png in the plugin folder and reporting the wrong message for the shadow-url. * it did set me completely on the wrong track. * the %1 is reporting this ([http://thewebsite.com/wp-content/uploads/leaflet-maps-marker-icons](http://thewebsite.com/wp-content/uploads/leaflet-maps-marker-icons)) * whereas it should be reporting * [http://thewebsite.com/wp-content/plugins/leaflet-maps-marker/leaflet-dist/images](http://thewebsite.com/wp-content/plugins/leaflet-maps-marker/leaflet-dist/images) * see the compatibility-check.php * Best regards, BackuPs * Thread Starter [BackuPs](https://wordpress.org/support/users/backups/) * (@backups) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-message-in-backend/#post-3381669) * Hi * if you set the check for the marker-shadow to * $shadow_icon_url= WP_PLUGIN_DIR .’/leaflet-maps-marker/leaflet-dist/images/marker- shadow.png’; * you can use the * $shadow_icon_url_exists = file_exists($shadow_icon_url); * and you dont need curl to acces that file. * however the error message still does not match the actual file-check. I did not adjust that * Best regards, BackuPs * Thread Starter [BackuPs](https://wordpress.org/support/users/backups/) * (@backups) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-message-in-backend/#post-3381672) * Hmm that does not work when the user sets its own shadow icon….. brr * ok i will remove the check in my spoof site only. * Thanks for settings me in the right direction. * It leaves you with the wrong error message the %1 to fix. * have a nice day. * Plugin Author [Robert Seyfriedsberger](https://wordpress.org/support/users/harmr/) * (@harmr) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-message-in-backend/#post-3381684) * Hi, thanks for analyzing – will check your suggestions. ad file_exists: this doesnt work for urls as far as I know and only for paths on server. Anyway: I will add an option to disable admin notices completely in the next release… regards, Robert * Thread Starter [BackuPs](https://wordpress.org/support/users/backups/) * (@backups) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-message-in-backend/#post-3381701) * Hi Robert, * sorry for the spamming. It was my analysing process. Thanks for adding the option. I already grasped that the file_exist did not work because of the url-path which can be added in the option. * But what if they dont have curl installed? i dont know if the get_headers function will be a better solution. * Thanks anyway. * have a great weekend for whats left of it. * Plugin Author [Robert Seyfriedsberger](https://wordpress.org/support/users/harmr/) * (@harmr) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-message-in-backend/#post-3381702) * No need to excuse – this is no spamming for me – appreciate your infos. * If not curl is installed, the check wont be executed. I already implemented this fall back solution with the latest release. I did quite a lot research and found the curl approach with checking for http status 200 the most efficient one for my solution. Ad get_headers: cant remember if I also checked this one. It seems that this would also work, but according to [http://php.net/manual/de/function.get-headers.php](http://php.net/manual/de/function.get-headers.php)( comment #2) this would be the slowest solution… best regards, Robert Viewing 10 replies - 1 through 10 (of 10 total) The topic ‘Error message in backend’ is closed to new replies. * ![](https://ps.w.org/leaflet-maps-marker/assets/icon.svg?rev=970936) * [Leaflet Maps Marker (Google Maps, OpenStreetMap, Bing Maps)](https://wordpress.org/plugins/leaflet-maps-marker/) * [Frequently Asked Questions](https://wordpress.org/plugins/leaflet-maps-marker/#faq) * [Support Threads](https://wordpress.org/support/plugin/leaflet-maps-marker/) * [Active Topics](https://wordpress.org/support/plugin/leaflet-maps-marker/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/leaflet-maps-marker/unresolved/) * [Reviews](https://wordpress.org/support/plugin/leaflet-maps-marker/reviews/) * 10 replies * 2 participants * Last reply from: [Robert Seyfriedsberger](https://wordpress.org/support/users/harmr/) * Last activity: [13 years, 4 months ago](https://wordpress.org/support/topic/error-message-in-backend/#post-3381702) * Status: not resolved
