asp.net - MVC Action giving IIS access denied error -

i have strange issue affecting 1 of actions in specific controller.

all other actions in controller post fine, when post view of 1 particular action error:

http error 403.0 - modsecurity action not have permission view directory or page.

this confuses me views post in similar fashion , use same web.config files.

my view:

<form action="/admin/editmenus" method="post" class="form-horizontal"> ....standard form controls in here..... </form> 

my controller:

[httppost] public actionresult editmenus(string mondayweek1regulardescription,             string mondayweek1regularcost,             string mondayweek1vegetariandescription,             string mondayweek1vegetariancost,             string mondayweek1nocarbdescription,             string mondayweek1nocarbcost,             string mondayweek1kiddiesdescription,             string mondayweek1kiddiescost,             string tuesdayweek1regulardescription,             string tuesdayweek1regularcost,             string tuesdayweek1vegetariandescription,             string tuesdayweek1vegetariancost,             string tuesdayweek1nocarbdescription,             string tuesdayweek1nocarbcost,             string tuesdayweek1kiddiesdescription,             string tuesdayweek1kiddiescost,             string wednesdayweek1regulardescription,             string wednesdayweek1regularcost,             string wednesdayweek1vegetariandescription,             string wednesdayweek1vegetariancost,             string wednesdayweek1nocarbdescription,             string wednesdayweek1nocarbcost,             string wednesdayweek1kiddiesdescription,             string wednesdayweek1kiddiescost,             string thursdayweek1regulardescription,             string thursdayweek1regularcost,             string thursdayweek1vegetariandescription,             string thursdayweek1vegetariancost,             string thursdayweek1nocarbdescription,             string thursdayweek1nocarbcost,             string thursdayweek1kiddiesdescription,             string thursdayweek1kiddiescost,             string fridayweek1regulardescription,             string fridayweek1regularcost,             string fridayweek1vegetariandescription,             string fridayweek1vegetariancost,             string fridayweek1nocarbdescription,             string fridayweek1nocarbcost,             string fridayweek1kiddiesdescription,             string fridayweek1kiddiescost,             string mondayweek2regulardescription,             string mondayweek2regularcost,             string mondayweek2vegetariandescription,             string mondayweek2vegetariancost,             string mondayweek2nocarbdescription,             string mondayweek2nocarbcost,             string mondayweek2kiddiesdescription,             string mondayweek2kiddiescost,             string tuesdayweek2regulardescription,             string tuesdayweek2regularcost,             string tuesdayweek2vegetariandescription,             string tuesdayweek2vegetariancost,             string tuesdayweek2nocarbdescription,             string tuesdayweek2nocarbcost,             string tuesdayweek2kiddiesdescription,             string tuesdayweek2kiddiescost,             string wednesdayweek2regulardescription,             string wednesdayweek2regularcost,             string wednesdayweek2vegetariandescription,             string wednesdayweek2vegetariancost,             string wednesdayweek2nocarbdescription,             string wednesdayweek2nocarbcost,             string wednesdayweek2kiddiesdescription,             string wednesdayweek2kiddiescost,             string thursdayweek2regulardescription,             string thursdayweek2regularcost,             string thursdayweek2vegetariandescription,             string thursdayweek2vegetariancost,             string thursdayweek2nocarbdescription,             string thursdayweek2nocarbcost,             string thursdayweek2kiddiesdescription,             string thursdayweek2kiddiescost,             string fridayweek2regulardescription,             string fridayweek2regularcost,             string fridayweek2vegetariandescription,             string fridayweek2vegetariancost,             string fridayweek2nocarbdescription,             string fridayweek2nocarbcost,             string fridayweek2kiddiesdescription,             string fridayweek2kiddiescost,             string week1startdate,             string week2startdate,             string orderby,             string menustart,             string menuend             ){ ...standard control posting model... return view(); } 

the error me says must iis related fact other actions in same controller work fine , it's 1 tells me else....like said works locally fine on server gives error.

go web.config ftp , write following line in web.config:

<system.webserver>   <validation validateintegratedmodeconfiguration="false" />   <modsecurity enabled="false" configfile="c:\inetpub\wwwroot\owasp_crs\modsecurity.conf" /> </system.webserver>
