I’m using RW 8.3 with Stacks 3.6.8. My website is built using the free Panoramic theme from ThemeFlood and the Kalendar stack from Weavium linked to an iCloud calendar. The site operates without any problems, except… Kalendar is slow to load events on a desktop or laptop, but it does work. On a tablet or phone (specifically iPad or iPhone using Safari) the calendar does load, but any attempt to move to another month will crash the web page after the following sequence: 1. Tap right arrow to load next month - shows error “This web page was reloaded because a problem occurred” 2. Tap right arrow again - shows error “A problem repeatedly occurred on “https:// [www.xxxx.co.uk/club/calendar/“.”](http://www.xxxx.co.uk/club/calendar/%E2%80%9C.%E2%80%9D) Linking my iPhone to the desktop Safari Develop feature showed that 3 errors were generated: 1. [Error] Failed to load resource: the server responded with a status of 404 () (badge\_smaller@2x.png, line 0) [https://www.wnsc.co.uk/club/rw\_common/images/badge\_smaller@2x.png](https://www.wnsc.co.uk/club/rw_common/images/badge_smaller@2x.png) 2. [Error] Failed to load resource: the server responded with a status of 404 () (blank@2x.gif, line 0) [https://www.xxxx.co.uk/club/rw\_common/themes/panoramic/images/blank@2x.gif](https://www.xxxx.co.uk/club/rw_common/themes/panoramic/images/blank@2x.gif) 3. [Error] Failed to load resource: the server responded with a status of 404 () (ical.min.js.map, line 0) [https://www.xxxx.co.uk/club/calendar/files/ical.min.js.map](https://www.xxxx.co.uk/club/calendar/files/ical.min.js.map) None of the 3 files referenced occur in my RW project file. Although there is a badge\_smaller.png and a blank.gif at the given locations. Is this a problem with Kalendar or the Panoramic theme? Have just tried duplicating badge\_smaller.png and blank.gif as badge\_smaller@2x.png and blank@2x.gif. This had no affect at all, the crash still occurred but the only error shown in Develop was [Error] Failed to load resource: the server responded with a status of 404 () (ical.min.js.map, line 0) [https://www.xxxx.co.uk/club/calendar/files/ical.min.js.map](https://www.xxxx.co.uk/club/calendar/files/ical.min.js.map) ---

The 404 errors `@2xpng` and `@2x.gif` are looking for the “Retina” ready images for the iPhone and shouldn’t be causing the issue you described. At worst would have an image not found, but the rest of the page would render OK. The 404 errors for `min.js.map` won’t cause a problem, `.map` files are only used for debugging minified files. This is caused more than likely by the process a stack or theme uses minifying the javascript. Most of these processes create a "`.map` file to help web tools put things back together while using a debugger. Not having them will have no effect on the page rendering correctly. > [@adger](#): > > Is this a problem with Kalendar or the Panoramic theme? Without a real URL to a page, it would be impossible to say what is causing the problems. My guess is the “no harm” 404 for the `.map` is the stack(just going on the URL file location). The other 404’s `@2` hard to say. But none of these I think are causing the big issue. ---

If you send me a contribution, I’ll give you a copy of Panoramic theme in return that does not include retina.js and associated plug-ins. That will banish the ‘@2x’ image errors for sure. ---

@teefers, thanks for taking the time to explain that, it has helped a great deal. It made me focus on the Kalendar stack. I compiled a test calendar with recurring events limited by a set end date, instead of the active calendar which has recurring monthly events with no end. Now I know Kalendar does not handle infinitely recurring events well at all. @willwood again, thanks I’ll be in touch to arrange that. Much appreciated. ---
