I'm using the thesis class (https://ctan.org/pkg/thesis?lang=de) for my thesis in LaTex but I have some problems. Overleaf didn't know the thesis class so I had to load up the class by my self on the LaTex project. Howsoever I have problems with the label of figures, tabels and the table of symbols (for which I'm using the useagepackage "listofsymbols"). I have for the defualt language of the whole file ngerman but the labels are in english ("Fig" instead of "Abb" e.g.). Furthermore the table of symbols isn't a "chapter" by his own (like the table of contents e.g.) - maybe the usepackage "listofsymbols" doesn't work with this class?
Thanks.
articleorreportmight be a good choice. If you want/need more customisation options, you can try the KOMA-Script classesscrartclorscrreprt.memoiris another popular powerful document class. I'd stay away from everything that calls itself 'thesis class': Those are often heavily customised and can be tricky to modify. Sometimes they aren't maintained or supported any more. In this particular case the class is just outdated. – moewe Aug 19 '20 at 17:36
