making the error record, the identifier, the version number of the related digital content item, and the related fingerprint data, available.

2. The method according to claim 1, wherein the fingerprint data comprises at least one selected from the group consisting of:

the content identifier, the content version number, a web page identifier, a web page version number, the type of request, a selected dialog language, a locale, a user identifier, a role associated with the user identifier, and a permission associated with the user identifier.

3. The method according to claim 1, further comprising passing on the fingerprint data of the request to services receiving sub-requests of the request.

4. The method according to claim 1, further comprising:

determining a common subset of attributes values of the error record and earlier stored error records; and

relating the error record to earlier stored error records in the case that a predefined number of attribute values are identical between the error record and the earlier stored error records.

5. The method according to claim 4, further comprising sending an alert to a developer account relating to the digital content item having caused the creating of the error record.

6. The method according to claim 4, wherein making the error record available comprises making the identifier, the version number of the digital content item, and the fingerprint data of the earlier stored error records available.

7. The method according to claim 1, further comprising:

deactivating a digital content item, having caused the creation of the error records; and

activating the digital content item having the same identifier and an earlier version number.

8. The method according to claim 1, further comprising:

generating hypothetical fingerprint data for a digital content item undergoing a current change;

comparing the hypothetical fingerprint data with a database of fingerprint data associated with error records; and

generating a warning message for the current change if a predefined number of attributes values of the hypothetical fingerprint data and one of the fingerprint data of the database match.

9. The method according to claim 8, further comprising:

comparing the hypothetical fingerprint data of the current change with fingerprint data of error records by calculating a distance vector or performing a cognitive classification for attribute values of each hypothetical fingerprint data set and fingerprint data from the error records resulting in a comparison result; and

making the comparison result available for review.

10. The method according to claim 9, further comprising deriving rules based on the distance vector or the cognitive classification of comparing earlier error records.

11. A system for enabling a root cause analysis for an error originating in a content management system, the content management system being adapted for a creation and a change of a plurality of digital content items, the system comprising:

a memory medium comprising program instructions;

a bus coupled to the memory medium; and

a processor, for executing the program instructions, that when executing the program instructions causes the system to;

store an identifier and a version number for each digital content item undergoing a change associated with the digital content item;

render a web page comprising the digital content item, wherein the identifier and the version number are invisibly included in the web page;

include the identifier and the version number in a request based on the rendered web page comprising the digital content item;

store fingerprint data associated with the request;

create an error record in the case that during an execution of the request an execution error occurs, wherein the error record comprises the identifier, the version number of the digital content item, and the related fingerprint data; and

make available the error record, the identifier, the version number of the related digital content item, and the related fingerprint data.

12. The system according to claim 11, wherein the fingerprint data comprises at least one selected from the group consisting of:

the content identifier, the content version number, a web page identifier, a web page version number, the type of request, a selected dialog language, a locale, a user identifier, a role associated with the user identifier, and a permission associated with the user identifier.

13. The system according to claim 11, the instructions further causing the system to pass on the fingerprint data of the request to services receiving sub-requests of the request.

14. The system according to claim 11, the instructions further causing the system to:

determine a common subset of attributes values of the error record and earlier stored error records; and

relate the error record to earlier stored error records in the case that a predefined number of attribute values are identical between the error record and the earlier stored error records.

15. The system according to claim 14, the instructions further causing the system to send an alert to a developer account, relating to the digital content item, having caused the creating of the error record.

16. The system according to claim 14, the instructions further causing the system to make available the identifier, the version number of the digital content item, and the fingerprint data available of the earlier stored error records.

17. The system according to claim 11, the instructions further causing the system to;

deactivate a digital content item having caused the creation of the error records; and
