| 54 | === Customized Templates === |
| 55 | |
| 56 | Sometimes, the ClearSilver templates files have been locally modified, and placed in a special location referred to by the `[trac] templates_dir` configuration setting. |
| 57 | |
| 58 | When upgrading to a newer version, changes in the Trac source are usually concerning ''both'' the Python source code and the template markup, so they must be kept in sync. |
| 59 | Upgrading the code base and still using the old templates (even not customized!) is a recipe for trouble: |
| 60 | - ''Link and images missing for folders in the TracBrowser component (and tooltip saying "Access Denied")'' (#3915) |
| 61 | - ''Report execution failed: Report ... has no SQL query'' (#3715) |
