Generate PDF Button

We had a working "Generate PDF" button for some of our cases. The button has stopped working properly. I checked the Apex for the visualforce page, but when trying to preview, I get the following message "List has no rows for assignment to SObject." I know I'm missing something, but I can't seem to find it. Any help is greatly appreciated. This is the current code:
<apex:page standardController="Case" extensions="DmcaCaseExt" renderAs="pdf" language="{!languageCode}">
  <apex:pageBlock >
      <apex:pageBlockSection >
      <h2>Digital Millenium Copyright Act Notice Form</h2>
      <apex:pageBlockSection >
        <p>The Digital Millennium Copyright Act (”DMCA”) is a United States copyright law that provides guidelines for online service providers in case of copyright infringement. Below is the information that should be present in these notices. It is designed to make submitting notices of alleged infringement to us as straightforward as possible while reducing the number of notices that we receive that are fraudulent or difficult to understand or verify. The form of notice specified below is consistent with the DMCA, which can be found at the U.S. Copyright Office website,</p>
        <p>To file a notice of infringement with us, you must provide us with the items specified below. Please note that you will be liable for damages (including costs and attorneys' fees) if you materially misrepresent that the material is infringing your copyright. Accordingly, if you are not sure whether material infringes your copyright, we suggest that you first contact an attorney.</p>
        <p>This notice and any attachments we receive will be forwarded to the alleged infringer, who will then have the opportunity to file a counter notification pursuant to Sections 512(g)(2) and (3) of the DMCA. Should a properly filed counter notifica- tion be filed, you will be notified and have 10 business days within which to file for a restraining order in Federal Court to prevent the reinstatement of the material.</p>

Please create a Visualforce Custom button in Case Layout. Than click that custom button you will get an output......!

It seems you have a apex controller named as DmcaCaseExt, there is some issue in the apex class itself. Can you share that code ?

This error occurs when your SOQL query doesn't returns any row.

For ex - 
ObjectSample__c sample = [SELECT Id from ObjectSample__c where Some := Value];

To be on safer side you should write this to avoid the exception - 
ObjectSample__c[] samples = [SELECT Id from ObjectSample__c where Some := Value];

Refer this link ( more details on this error.

You are getting this error because the query which you have written can not return anything from the object.
You can put the query in try catch block so that you will not receive the error.
Case c= new Case();
        c= [SELECT id from Case limit 1];
   catch(Exception e){
       c= new Case();
        system.debug('------'+c.Status); // will return null 

Hope this will help you.

I am Chris S's colleague. Here is the Apex Class DmcaCaseExt:
public class DmcaCaseExt {
    public Case dmcaCase {get; private set;}
    public String languageCode {get; private set;}
    public DmcaCaseExt(ApexPages.StandardController controller) {
        Id caseId = ((Case)controller.getRecord()).Id;
        dmcaCase = [select Id, First_Name__c, Last_Name__c, SuppliedEmail, SuppliedPhone, Language__c, DMCA_Complainant_Title__c, QC_Complainant_Address__c, QC_Complainant_Country__c, SuppliedCompany,
                    DMCA_Description__c, DMCA_Sworn_Confirm__c, DMCA_Accurate_Confirm__c,  DMCA_Signed_Date__c, DMCA_Signature__c, Problem_URL__c from Case where Id = :caseId];
    public PageReference setLocale(){
        if(dmcaCase.Language__c == 'German'){
            languageCode = 'de';
            return Page.DmcaPDF_DE;
        } else if(dmcaCase.Language__c == 'French'){
            languageCode = 'fr';
            return Page.DmcaPDF_FR;
        } else if(dmcaCase.Language__c == 'Spanish'){
            languageCode = 'es';
            return Page.DmcaPDF_SP;
        } else if(dmcaCase.Language__c == 'Italian'){
            languageCode = 'it';
            return Page.DmcaPDF_IT;
        } else if(dmcaCase.Language__c == 'Dutch'){
            languageCode = 'nl';
            return Page.DmcaPDF_NL;
        } else {
            languageCode = 'en';
            return Page.DmcaPdf_EN;

And the custom 'Generate PDF' button on our Case layout 'opens in existing window without sidebar' with a 'URL' content source and redirects here:
It looks like the problem is coming from the dmcaCase variable assignment, but we're not sure how to implement the suggested solutions. We haven't changed this code in years, and this problem started happening on July 28. Any tips? Thanks much!
