GRAV crashes with `Call to undefined method Symfony\Polyfill\Mbstring\Mbstring::mb_ord();`
codiflow opened this issue · comments
After the recent update of GRAV and all plugins (Grav v1.5.8 - Admin v1.8.19) I got the following error message when I tried to edit any page content:
Call to undefined method Symfony\Polyfill\Mbstring\Mbstring::mb_ord();
Stack trace:

To solve this issue I tried everything like installing all polyfill/php/mbstring/iconv packages via apt but the error still persisted.
I checked the availability of the iconv extension with the command php7.0 -ri iconv and the result was as follows:
iconv
iconv support => enabled
iconv implementation => glibc
iconv library version => 2.24
Directive => Local Value => Master Value
iconv.input_encoding => no value => no value
iconv.output_encoding => no value => no value
iconv.internal_encoding => no value => no value
After several hours of searching for the cause of the problem I found out that it was gone after disabling this SEO plugin...
do u have mbstring enabled in your php.ini?
Looks so
php7.0 --ri mbstring
mbstring
Multibyte Support => enabled
Multibyte string engine => libmbfl
HTTP input encoding translation => disabled
libmbfl version => 1.3.2
oniguruma version => 5.9.6
mbstring extension makes use of "streamable kanji code filter and converter", which is distributed under the GNU Lesser General Public License version 2.1.
Multibyte (japanese) regex support => enabled
Multibyte regex (oniguruma) backtrack check => On
Multibyte regex (oniguruma) version => 5.9.6
Directive => Local Value => Master Value
mbstring.language => neutral => neutral
mbstring.detect_order => no value => no value
mbstring.http_input => no value => no value
mbstring.http_output => no value => no value
mbstring.internal_encoding => no value => no value
mbstring.substitute_character => no value => no value
mbstring.func_overload => 0 => 0
mbstring.encoding_translation => Off => Off
mbstring.http_output_conv_mimetypes => ^(text/|application/xhtml\+xml) => ^(text/|application/xhtml\+xml)
mbstring.strict_detection => Off => Off
Strange about all this stuff is that it worked like a charm before the GRAV / SEO-plugin update
Looks like this was solved in another thread!
