Need more detail regarding this. This message is custom not actual. So for debugging purpose can you write a core file and update original error message here?

  1. vendor/magento/module-review/Controller/Product/Post.php

Line 69: add $e->getMessage() which is original exception. Now should looks like:

} catch (\Exception $e) {
    $this->messageManager->addError(__('We can\'t post your review right now.'.$e->getMessage()));
  1. Other case is if form validation is wrong. That means Title, Nickname, and Detail should be required field. So added something error message here to.

if (is_array($validate)) {
    foreach ($validate as $errorMessage) {
} else {
    $this->messageManager->addError(__('We can\'t post your review right now. --- TEST'));

Note: After you got an actual exception, then please undo your core change with the original code. Core file modification is not good.

  • Thank you, I added .$e->getMessage())); this code. but still same error.

  • Did you check to validate method? vendor/magento/module-review/Model/Review.php::validate?

  • Sorry, I tried again. And I add .$e->getMessage())); this code. And I cleaned cache. Now I saw this message. We can't post your review right now.SQLSTATE[21000]: Cardinality violation: 1241 Operand should contain 1 column(s), query was: SELECT rating_option.* FROM rating_option WHERE (rating_option.option_id='38', '34', '45')

Seems this SQL error

Missed data form some REVIEW* tables.

Maybe after cleanup test data :)

Solution - setup fresh & clean Magento 2.

Copy SQL export of data for tables review_status & review_entity,

import to DB of Magento with review bug.

But be carefull with SQL query.
