Hi there,
first, I'd like to thank you for the possibility to use your calendar as free. I'm providing an website with my own money but can't spend it for all extensions I like to use.
Now to the problem.
Every year it is frustrating to import entries to the calendar, because there are everytime new problems to solve. I use the import function at 4th time and tried it in the same way like 2014, 2013 and 2012. The txt-file looks like this (I used the file from last year with updated dates):
CATEGORIES,DESCRIPTION,LOCATION,SUMMARY,CONTACT,X-EXTRAINFO,DTSTART,DTEND,TIMEZONE,RRULE,
"CVJM","","Eibach ","hohes c Gottesdienst","","",20160716T193000,,"Europe/Berlin","",
"Schützenverein","","Schützenhaus ","Königsschießen","","",20160717T110000,,"Europe/Berlin","",
"OGV","","Vereinsheim ","Sommerschnittkurs","","",20160806T100000,,"Europe/Berlin","",
I tried to create a new calendar with this file an get this error:
Warning: curl_setopt() [function.curl-setopt (function.curl-setopt)]: CURLOPT_FOLLOWLOCATION cannot be activated when

1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right
syntax to use near ')' at line 1 SQL=DELETE FROM jos_jevents_catmap where evid = 343 AND catid NOT IN ()
After that error I had a look at the entries "which are made".
Only the first entry in the txt-file is displayed at the backend.
I deleted it and want to delete the calendar too, but it is not possible, because it gives me the feedback that there will be some lost entries when it would be deleted.
But I can't find any entries in the calendar, so I can't delete them first.
There is also no way to save a new txt-file or update the old in the existing calendar.
I am not an specialist and do not know where the problem is. At my webserver or in any installation of Joomla/JEvents.
I hope you can help me solve the problem(s).
In this way I have a feature request for you.
I also use ACYMailing. There you can import new users with comma separatet fields in a simple text area by copy and paste. Additional it is not needed to ad " at every data field.
See this example:

It would be so much easier for non professional useres whith this feature in JEvents...
But more: I didn't know any other system who uses the date-format yyyymmddThhmmss. It's a lot of work for non-specialists to convert the ordinary human-written dd.mm.yyyy to this. This could be much more comfortable.
