I ran into another issue right after that and I am not sure whether it is related or not:
Warning Error: transliterator_transliterate(): Could not create transliterator with ID "Any-Latin; Latin-ASCII; [\u008
0-\u7fff] remove" (transliterator_create: unable to open ICU transliterator with id "Any-Latin; Latin-ASCII; [\u0080-\
u7fff] remove": U_INVALID_ID) in [/home/www/arpes.info/blog/vendor/cakephp/cakephp/src/Utility/Text.php, line 1070]
I read that one needs to install/upgrade ICU library, but my provider is reluctant to do that. Is there any other way?
