I am having a serious problem that I do not know how to solve. I am using overleaf and the bristol template to write my thesis. I am mostly writing in english but I need to write an abstract in greek. If i add greek to babel instantly I get compilation error. I attach the log for further insight. Thank you in advance.

misspelled it (e.g., `hobx'), type `I' and the correct

spelling (e.g., `Ihbox'). Otherwise just continue,

% File: memoirthesis.tex

% Author: Victor Brena

% Description: Contains the thesis template using memoir class,

% which is mainly based on book class but permits better control of 

% chapter styles for example. This template is an adaptation and 

% modification of Oscar's.

% 

% Memoir is a flexible class for typesetting poetry, fiction, 

% non-fiction and mathematical works as books, reports, articles or

% manuscripts. CTAN repository is found at:

% http://www.ctan.org/tex-archive/macros/latex/contrib/memoir/

%

%

% UoB guidelines for thesis presentation were found at:

% http://www.bris.ac.uk/esu/pg/pgrcop11-12topic.pdf#page=49

%

% UoB guidelines:

%

% The dissertation must be printed on A4 white paper. Paper up to A3 may be used

% for maps, plans, diagrams and illustrative material. Pages (apart from the

% preliminary pages) should normally be double-sided.

%

% Memoir class loads useful packages by default (see manual).
