Installed version 15.5.0.107 and the left side menu is not displayed in the administration console opened in a web browser.
When Serv-U 15.5 was installed (non-English version), the sidebar options did not load when opening the management console. This issue occurs due to a bug in Serv-U 15.5. Reports are related to Spanish and French version, but this can impact other languages. SolarWinds is tentatively planning to fix this issue in the next available release. As a workaround, please install Serv-U in English.
